DETAILED DESCRIPTION

The Machine Learning Portfolio Simulating and Optimizing Apparatuses, Methods and Systems (hereinafter “MLPO”) transforms machine learning simulation request, decision tree ensembles training request, expected returns calculation request, portfolio construction request, predefined scenario construction request, portfolio returns visualization request inputs, via MLPO components (e.g., MLSSP, DTET, ERC, PC, PSC, SPRV, BPRV, PRV, ARMC, etc. components), into machine learning simulation response, decision tree ensembles training response, expected returns calculation response, portfolio construction response, predefined scenario construction response, portfolio returns visualization response outputs. The MLPO components, in various embodiments, implement advantageous features as set forth below.

Introduction

The MLPO provides unconventional features (e.g., executing tradeable transactions to create an optimized portfolio based on expected returns simulated using machine learning techniques, a SQL database calculation engine) that were never before available in machine learning and database systems.

Tail-events have rare historical occurrence. They are difficult to model and forecast. However, they can be an essential part of resilient decision processes. The MLPO demonstrates unique abilities to model variations in volatilities and dependency structures across factors and over different time periods; provides rich estimates of tail-event; enables conditional outcomes of tail-events; and uses advanced linear and non-linear optimization processes for superior decision support. The optimization results provide model recommended solutions, such as for portfolio construction.

The MLPO presents the latest innovations in two core capabilities of investment management: 1) simulation driven investment insights and decision support and 2) machine driven portfolio allocation guidance. It combines the latest machine learning methods with leading-edge cloud computing techniques. It enables differentiations across many business units: analytics and insights to power a commercial electronic bond trading platform, power tools for evaluating portfolio construction bias, smart Bond Ladder products, and/or the like.

In various embodiments, the MLPO may include one or more of the following features:

1 Maximizes the usage of high frequency historical data

a. Machine learning processes to impute missing data (e.g., in order to preserve higher frequency time-series data with gaps, and maximize the utility of all available historical data)

b. Flexible periodicity with overlapping techniques

2. Combines a mixer of copulas, flexible marginal distributions, rejection sampling and parallel computing for a single simulation engine which

a. Models changes in correlations and volatilities for “fat tail” events (e.g., using massive parallel computing to concurrently perform simulation and/or conditional simulation and/or stress scenario generations over cloud computing infrastructure)

b. Generates insights on the conditional impact of diverse factors on tail-events and volatilities

3. Allows calibration to forward-looking signals 4. Allows domain experts to incorporate their subjective views 5. Simulates longer horizon, multi-period outcomes with path dependency (e.g., using massive parallel computing frameworks in path-dependent, multi-period simulation to capture joint seasonality and mean-reversion tendencies across factors) 6. Preserves the cadence of historical cycles in forward-looking simulation paths 7. Allows forward-looking factor views to drive optimization results 8. Applies “simulation-data-driven” approach for tailed-constrained portfolio optimization (e.g., to recommend solutions allowing tail-risk, tradability controls, etc.). In one embodiment, applies linear relaxation to CVaR constraints and mixed integer linear programming for optimization problem solving. In another embodiment, applies stochastic optimizer with VaR or CVaR and integer constraints to solve a non-linear optimization problem.

In some embodiments, the MLPO may implement a database calculation engine for calculating simulation data. The database calculation engine may be a SQL-based solution that effectively utilizes different data reduction and parallel execution techniques to reduce the overall response time. Instead of using a dedicated high-performance platform (e.g., IBM Netezza Data Appliance) the database calculation engine may be used for simulation calculation providing a faster, streamlined, cost effective and scalable solution (e.g., using Oracle RDS on Cloud) that provides calculation results in substantially less amount of time. Further, the database calculation engine eliminates having to maintain a complex infrastructure and applications associated with using a dedicated high-performance platform, and having to pay for additional licensing and maintenance costs.

The database calculation engine solution is faster as data does not have to be transferred outside of the database with an innovative data reduction strategy that applies to simulation generation, less complex as the solution may run entirely on a database, scalable as the solution effectively utilizes vertical scalability offered by RDS on Cloud and more maintainable.

In some implementations, the database calculation engine may provide the following features:

-   -   A novel way of calculating simulation data using a SQL only         solution.     -   Application of unique data reduction techniques applicable         specifically to the way data is aggregated for simulation data.     -   Use of vertical scalability and concurrency offered by Oracle         RDS on Cloud for faster execution.     -   Processing that happens at the database level, eliminating         having to transfer data outside to external systems and         maximizing processing of data using cloud computing.     -   Faster and more cost effective than using high-performance         platforms.

In some implementations, the database calculation engine may utilize various innovative data reduction, scaling and parallel computing techniques (e.g., techniques to use global temporary tables and sessions, data reduction techniques to drastically reduce the amount of data used for processing thus lowering processing time, and several other data parallelization techniques used for generating simulation data):

-   -   Use of Multiple Batches to achieve higher degree of parallelism         (DOP)     -   Use of Global Temporary Tables (GTT) to be able to run batch in         multiple sessions and limit temporary storage requirements     -   Use of Data Reduction techniques to limit full table scans for         joins between Factor Exposure and Factor Simulation table     -   Use of Parallel Query to parallelize generation of Asset         Simulation and Contribution to Value at Risk data     -   Use of Parallel DML to parallelize inserting data related to         Asset Simulation and Contribution to Value at Risk     -   Use of DDL for faster execution of delete statements to speed up         cleanup of global temporary tables

FIGS. 2A-B show a logic flow illustrating embodiments of a machine learning simulated scenario processing (MLSSP) component for the MLPO. In FIG. 2A, a machine learning simulated scenario processing request may be obtained at 201. For example, the machine learning simulated scenario processing request may be obtained as a result of an administrative user requesting generation of a set of simulated scenarios.

A rolling window period length may be determined at 205. In one embodiment, historical data may be analyzed to calculate changes to a set of market factors during each rolling window period of a specified rolling window period length. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine historical data to analyze (e.g., based on the value of the historical_data field) and/or the rolling window period length to use for analysis (e.g., based on the value of the rolling_window_period_length field). For example, the machine learning simulated scenario processing request may specify that the last 30 years of historical data should be analyzed using 6 month rolling window periods.

Market factors to process may be determined at 209. For example, market factors may include interest rates, credit spread, oil price, equity indices, and/or the like, and changes to the market factors during a rolling window period jointly describe a market scenario (e.g., a historical market scenario for historical changes, a simulated market scenario for simulated changes). In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the market factors to process (e.g., based on the value of the market_factors field). In another implementation, a set of default market factors to process may be specified in a configuration setting.

A determination may be made at 213 whether there remain market factors to process. In one implementation, each of the market factors may be processed. If there remain market factors to process, the next market factor (e.g., 6 month change in interest rates) may be selected for processing at 217.

A determination may be made at 221 whether there remain rolling window periods to analyze. In one implementation, historical data for the selected market factor may be analyzed during each of the rolling window periods. If there remain rolling window periods to analyze, the next rolling window period may be selected for analysis at 225. For example, the next rolling window period may be two specific time points (e.g., days) 6 months apart.

A determination may be made at 229 whether data for the selected rolling window period is available. In one implementation, this determination may be made based on whether historical data for the selected market factor is available for both time points (e.g., for both days) of the selected rolling window period.

If historical market factor data is unavailable for one or both time points (e.g., days) of the selected rolling window period, the missing data may be imputed using a machine learning (e.g., k-Nearest Neighbors (k-NN)) method at 233 based on market factor data for other time points (e.g., for other days). In one implementation, the k-NN method may be used to match records (e.g., a record may be a set of market factors for a time point) with missing data points (e.g., a missing data point may be a missing market factor data for a time point) in a multi-dimensional space. For example, the missing data for the selected market factor for a time point may be calculated as the average of values of the selected market factor for k nearest neighbors of the time point as determined based on similarity of the other market factors.

Change to the selected market factor during the selected rolling window period may be calculated at 237. In one implementation, the change to the selected market factor during the selected rolling window period may be calculated by determining the delta between values of the selected market factor at the two time points of the selected rolling window period. For example, the 6 month change in 5 year interest rates for the rolling window period between Jan. 7, 2019 and Jul. 8, 2019, may be calculated by subtracting the US Treasury 5 Year Par Yield on Jan. 7, 2019 from the US Treasury 5 Year Par Yield on Jul. 8, 2019. In another example, the 6 month change in 5 year interest rates for the rolling window period between Jan. 8, 2019 and Jul. 9, 2019, may be calculated by subtracting the US Treasury 5 Year Par Yield on Jan. 8, 2019 from the US Treasury 5 Year Par Yield on Jul. 9, 2019.

Once changes to each of the market factors during each of the rolling window periods are calculated, a determination may be made at 241 regarding the type of time period buckets to utilize. In one embodiment, fixed length time period buckets may be utilized. In another embodiment, variable length time period buckets may be utilized. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the type of time period buckets to utilize (e.g., based on the value of the time_period_bucket_type field).

If fixed length time period buckets are utilized, the length of time period buckets to utilize may be determined at 245. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the length of time period buckets to utilize (e.g., based on the value of the time_period_bucket_length field). For example, the machine learning simulated scenario processing request may specify that historical market scenarios generated from the last 30 years of historical data (e.g., using calculated changes from 237) should be split using 6 month long time period buckets, resulting in 60 time period buckets to process. It is to be understood that the length of time period buckets is independent of the rolling window period length (e.g., the two lengths may be the same or may be different).

If variable length time period buckets are utilized, time period buckets reflective of changes in volatilities and correlations of the historical data may be determined at 249. In one implementation, the time period buckets may be selected by judging the overall goodness of fit between simulated data from the time period buckets and historical data. KS tests and Cramer test may be performed jointly between the simulated market scenarios and the historical market scenarios. The splitting into time period buckets may support the objective function of minimizing the KS test values of the marginal distributions and Cramer test value of the multivariate distribution of simulated market scenarios vs. realized historical market scenarios. For example, the machine learning simulated scenario processing request may specify that historical market scenarios generated from the last 30 years of historical data (e.g., using calculated changes from 237) should be split by bucketing historical market scenarios from the same economic cycle (e.g., early cycle, mid cycle, late cycle, recession) together to summarize the changes in volatilities and correlation structure. In some implementations, the number of time period buckets may be determined by balancing the amount of historical data vs. the number of market factors. For example, given that data frequency is constant, as the number of market factors increases the time duration utilized for each time period bucket increases.

The historical market scenarios may be bucketed in accordance with the determined time period buckets at 253. In one implementation, each historical market scenario may be assigned a bucket identifier that specifies the time period bucket associated with the respective historical market scenario.

A determination may be made at 257 whether there remain time period buckets to process. In one implementation, each of the time period buckets may be processed. If there remain time period buckets to process, the next time period bucket (e.g., historical market scenarios associated with the next 6 month long time period bucket) may be selected for processing at 261.

A deep learning neural network for the selected time period bucket may be trained at 281. For example, the deep learning neural network may be a Gaussian-Mixture Variational Autoencoder. In one embodiment, the deep learning neural network may be trained to map historical market factor changes to latent space variables and/or to map latent space variables to simulated market factor changes. See FIG. 2B for additional details regarding training the deep learning neural network. See FIG. 3 for an exemplary deep learning neural network architecture.

The number of market scenarios to simulate may be determined at 289. For example, 1,000 scenarios may be simulated (e.g., resulting in 60,000 total simulated scenarios over 60 time period buckets). In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the number of market scenarios to simulate for each of the time period buckets (e.g., based on the value of the number_of_simulated_market_scenarios field). In another implementation, the number of market scenarios to simulate for each of the time period buckets may be specified in a configuration setting. In another implementation, the number of market scenarios to simulate may differ for different time period buckets. For example, the number of market scenarios to simulate may be determined as an AI-driven weight learned by minimizing the L2 Norm between real data and simulated data.

A determination may be made at 293 whether there remain market scenarios to simulate. If so, simulated data may be generated using latent space variables at 295. In one implementation, random values for latent space variables of the trained deep learning neural network may be generated. For example, a random value for a latent space variable of the trained deep learning neural network may be generated (e.g., by optimizing the number of perceptrons, the number of layers of the encoder and decoder neural networks, and/or the number of latent space variables with the objective function of minimizing the L2 Norm between generated market factor changes and historical market factor changes) from a Gaussian or Gaussian mixture distribution (e.g., from a multivariate Gaussian distribution) using the Python NumPy library (e.g., with three inputs including the number of samples to be generated, mean and variance from the encoder).

A set of simulated market factor changes may be generated from the simulated data using a neural network decoder of the trained deep learning neural network at 297. In one implementation, the generated random values of latent space variables may be fed through the neural network decoder of the trained deep learning neural network to obtain a set of simulated market factor changes (e.g., the set of simulated market factor changes may be referred to as a simulated market scenario).

The simulated scenario may be stored in a database at 299. In one implementation, the simulated scenario may be stored (e.g., in a batch with other simulated scenarios) via a scenario results store request.

FIG. 2B shows additional details regarding training the deep learning neural network. In FIG. 2B, the historical market scenarios (e.g., a set of calculated market factor changes for each rolling window period of the selected time period bucket) may be obtained at 202. In one implementation, a reference to a historical market factor changes data structure (e.g., an array of arrays where each element of the outer array corresponds to a training data point of historical market factor changes for a rolling window period, and each element of the inner array corresponds to a historical return of a market factor during the rolling window period) with the calculated historical market factor changes may be obtained.

A determination may be made at 206 whether there remain hyper-parameters options of the deep learning neural network to analyze. For example, the hyper-parameters of the deep learning neural network may include the number of layers and/or perceptrons in each layer of encoder and/or decoder, the dimensionality of latent space, and/or the like. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine hyper-parameters options to test (e.g., based on the value of the hyper_parameters_to_test field). If there remain hyper-parameters options to analyze, the next set of hyper-parameters (e.g., specified in a hyper_parameters_option field) for the deep learning neural network may be selected for testing at 210.

A determination may be made at 212 whether a termination condition for training the deep learning neural network has been reached. In various implementations, the termination condition may comprise one or more of a specified number of training iterations, a specified training time, a specified minimum deep learning neural network performance rank, and/or the like.

If the termination condition for training the deep learning neural network has not been reached, a determination may be made at 214 whether there remain more training data points to use for training the deep learning neural network. In one implementation, each of the training data points in the historical market factor changes data structure may be used for training. If there remain more training data points to use, the next training data point (e.g., historical market factor changes for a rolling window period) may be selected at 218.

Input and output layers of the deep learning neural network may be set to the selected training data point at 222. In one implementation, the input and output layers may be f-dimensional layers, where f is the number of market factors. For example, the input and output layers may be set to the values of the inner array of the historical market factor changes data structure corresponding to the selected training data point.

The deep learning neural network may be trained on the selected training data point using a variational autoencoder to generate a set of Gaussian-Mixture latent variables at 226. In one embodiment, the deep learning neural network may be trained using backpropagation with a specified loss function. In one implementation, the loss function may be chosen to minimize mean squared error of the Euclidean distances of individual market factors return values to the historical realized return values, and/or to minimize the variance of joint distributions across encoded market factors between simulated and historical markets in the latent space (e.g., the KT, divergence score). In one embodiment, the loss function on factor returns may be in the original factor space, while the KT, divergence constraint plays the role in the latent space (lower dimensional space) to map the encoded factors to Gaussian or Gaussian mixture distribution. In one implementation, the encoder and the decoder may be set to have the same structures and during the training process their weights may be synchronized, so that half of the total weights have to be learned to reduce the complexity of deep network training

Once the deep learning neural network is trained on the training data points, performance of the trained deep learning neural network may be evaluated at 230. For example, the performance of the trained deep learning neural network may be evaluated using a set of testing data points (e.g., available data points may be split into 75% training data points and 25% testing data points). In one embodiment, the trained deep learning neural network may be assigned a performance rank (e.g., a score). In one implementation, differences between market factor changes at the input layer and market factor changes at the output layer may be evaluated using the Kolmogorov-Smirnov (KS) test for individual market factors and/or Cramer test for joint distribution to calculate a performance score for the trained deep learning neural network. For example, for the KS test and/or the Cramer test, the lower the scores, the better the performance. Accordingly, the scores may be sorted in ascending order and performance of deep learning neural networks may be ranked in the hyperparameter tuning process such that the deep learning neural network with the optimal performance is the one with the highest rank.

If the termination condition for training the deep learning neural network has been reached, the next set of hyper-parameters, if any, for the deep learning neural network may be analyzed at 206.

The neural network with the optimal performance may be selected at 234. In one implementation, the deep learning neural network with the best (e.g., highest) performance rank may be selected to simulate market scenarios.

FIG. 3 shows an architecture for the MLPO. In FIG. 3, an embodiment of how a deep learning neural network may be structured is illustrated. The deep learning neural network may have an input layer 301. The input layer may be an f-dimensional layer, where f is the number of market factors. Market factor changes data provided to the input layer may be converted using an encoder 305 into latent space variables 310. The encoder may comprise one or more hidden layers, and the number of hidden layers and/or the number of perceptrons in each layer may be hyper-parameters tuned for optimal performance. The latent space variables may comprise a hidden layer of Gaussian mixtures, and the dimensionality of latent space may be a hyper-parameter tuned for optimal performance. In one embodiment, the latent space may be implemented using a Gaussian distribution and a mixture layer. The mixture layer may be designed to introduce richer correlations across encoded factors and thus approximately formulate a Gaussian mixture distribution. The simulation may be conducted by sampling from the Gaussian distribution, then the samples may be transferred to a near Gaussian mixture space via the mixture layer, and then sent to a decoder that maps to the original factor space. In another embodiment, the latent space may be implemented using a standard Gaussian mixture distribution (GM), where the mixture weights are hyper-parameters to be fine-tuned. The simulation may be conducted by sampling from the GM, and then the samples may be sent to a decoder. Latent space variables data may be converted using a decoder 315 into market factor changes data in an output layer 320. The decoder may comprise one or more hidden layers, and the number of hidden layers and/or the number of perceptrons in each layer may be hyper-parameters tuned for optimal performance. The output layer may be an f-dimensional layer, where f is the number of market factors.

FIG. 4 shows a logic flow illustrating embodiments of a machine learning simulated scenario processing (MLSSP) component for the MLPO. In FIG. 4, a machine learning simulated scenario processing request may be obtained at 401. For example, the machine learning simulated scenario processing request may be obtained as a result of an administrative user requesting generation of a set of simulated scenarios.

A rolling window period length may be determined at 405. In one embodiment, historical data may be analyzed to calculate changes to a set of market factors during each rolling window period of a specified rolling window period length. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine historical data to analyze (e.g., based on the value of the historical_data field) and/or the rolling window period length to use for analysis (e.g., based on the value of the rolling_window_period_length field). For example, the machine learning simulated scenario processing request may specify that the last 30 years of historical data should be analyzed using 6 month rolling window periods.

Market factors to process may be determined at 409. For example, market factors may include interest rates, credit spread, oil price, equity indices, and/or the like, and changes to the market factors during a rolling window period jointly describe a market scenario (e.g., a historical market scenario for historical changes, a simulated market scenario for simulated changes). In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the market factors to process (e.g., based on the value of the market_factors field). In another implementation, a set of default market factors to process may be specified in a configuration setting.

A determination may be made at 413 whether there remain market factors to process. In one implementation, each of the market factors may be processed. If there remain market factors to process, the next market factor (e.g., 6 month change in interest rates) may be selected for processing at 417.

A determination may be made at 421 whether there remain rolling window periods to analyze. In one implementation, historical data for the selected market factor may be analyzed during each of the rolling window periods. If there remain rolling window periods to analyze, the next rolling window period may be selected for analysis at 425. For example, the next rolling window period may be two specific time points (e.g., days) 6 months apart.

A determination may be made at 429 whether data for the selected rolling window period is available. In one implementation, this determination may be made based on whether historical data for the selected market factor is available for both time points (e.g., for both days) of the selected rolling window period.

If historical market factor data is unavailable for one or both time points (e.g., days) of the selected rolling window period, the missing data may be imputed using a machine learning (e.g., k-Nearest Neighbors (k-NN)) method at 433 based on market factor data for other time points (e.g., for other days). In one implementation, the k-NN method may be used to match records (e.g., a record may be a set of market factors for a time point) with missing data points (e.g., a missing data point may be a missing market factor data for a time point) in a multi-dimensional space. For example, the missing data for the selected market factor for a time point may be calculated as the average of values of the selected market factor for k nearest neighbors of the time point as determined based on similarity of the other market factors.

Change to the selected market factor during the selected rolling window period may be calculated at 437. In one implementation, the change to the selected market factor during the selected rolling window period may be calculated by determining the delta between values of the selected market factor at the two time points of the selected rolling window period. For example, the 6 month change in 5 year interest rates for the rolling window period between Jan. 7, 2019 and Jul. 8, 2019, may be calculated by subtracting the US Treasury 5 Year Par Yield on Jan. 7, 2019 from the US Treasury 5 Year Par Yield on Jul. 8, 2019. In another example, the 6 month change in 5 year interest rates for the rolling window period between Jan. 8, 2019 and Jul. 9, 2019, may be calculated by subtracting the US Treasury 5 Year Par Yield on Jan. 8, 2019 from the US Treasury 5 Year Par Yield on Jul. 9, 2019.

Once changes to each of the market factors during each of the rolling window periods are calculated, a determination may be made at 441 regarding the type of time period buckets to utilize. In one embodiment, fixed length time period buckets may be utilized. In another embodiment, variable length time period buckets may be utilized. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the type of time period buckets to utilize (e.g., based on the value of the time_period_bucket_type field).

If fixed length time period buckets are utilized, the length of time period buckets to utilize may be determined at 445. In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the length of time period buckets to utilize (e.g., based on the value of the time_period_bucket_length field). For example, the machine learning simulated scenario processing request may specify that historical market scenarios generated from the last 30 years of historical data (e.g., using calculated changes from 437) should be split using 6 month long time period buckets, resulting in 60 time period buckets to process. It is to be understood that the length of time period buckets is independent of the rolling window period length (e.g., the two lengths may be the same or may be different).

If variable length time period buckets are utilized, time period buckets reflective of changes in volatilities and correlations of the historical data may be determined at 449. In one implementation, the time period buckets may be selected by judging the overall goodness of fit between simulated data from the time period buckets and historical data. KS tests and Cramer test may be performed jointly between the simulated market scenarios and the historical market scenarios. The splitting into time period buckets may support the objective function of minimizing the KS test values of the marginal distributions and Cramer test value of the multivariate distribution of simulated market scenarios vs. realized historical market scenarios. For example, the machine learning simulated scenario processing request may specify that historical market scenarios generated from the last 30 years of historical data (e.g., using calculated changes from 437) should be split by bucketing historical market scenarios from the same economic cycle (e.g., early cycle, mid cycle, late cycle, recession) together to summarize the changes in volatilities and correlation structure. In some implementations, the number of time period buckets may be determined by balancing the amount of historical data vs. the number of market factors. For exampe, given that data frequency is constant, as the number of market factors increases the time duration utilized for each time period bucket increases.

The historical market scenarios may be bucketed in accordance with the determined time period buckets at 453. In one implementation, each historical market scenario may be assigned a bucket identifier that specifies the time period bucket associated with the respective historical market scenario.

A determination may be made at 457 whether there remain time period buckets to process. In one implementation, each of the time period buckets may be processed. If there remain time period buckets to process, the next time period bucket (e.g., historical market scenarios associated with the next 6 month long time period bucket) may be selected for processing at 461.

A determination may be made at 465 whether there remain market factors to process. In one implementation, each of the market factors may be processed. If there remain market factors to process, the next market factor (e.g., 6 month change in interest rates) may be selected for processing at 469.

A distribution to use for the selected market factor during the selected time period bucket may be determined using the selected market factor's goodness of fit at 473. For example, a distribution to use may be Gaussian, log-normal, and/or the like. In one implementation, goodness of fit calculation may be performed to determine which distribution fits the historical returns (e.g., the calculated changes) for each time bucket using Kolmogorov-Smirnov Test (KS test) and/or Cramer test. For example, the distribution to use may be determined as the one with the best KS test performance for each of the individual factor and/or Cramer test performance for the overall distribution.

The determined marginal distribution to use may be fitted to the historical returns of the selected market factor during the selected time period bucket at 477. For example, the determined marginal distribution to use may be a Gaussian distribution. Accordingly, μ and a of the Gaussian distribution may be determined. In one implementation, the Gaussian distribution may be fitted by calculating μ and a of the historical returns (e.g., of the calculated changes) of the selected market factor during the selected time bucket. In one embodiment, the fitting may be implemented using Apache Spark. In some implementations, the fitting for multiple time buckets may occur in parallel. For example, a mapper function that performs the fitting and simulation for each time bucket and utilizes group by on time buckets may be implemented as follows:

reducer_simulator = generate_reducer_func(sim_id, 1 + num_sim_row / num_buckets) us_tsy_sim = us_tsy.map(lambda x:  (x[0], x[2])).groupByKey(num_buckets).flatMap(reducer_simulator)

A copula for the processed market factors for the selected time period bucket may be determined at 481. For example, the copula may be utilized to capture the dependency structure between marginal distributions of the market factors during the selected time period bucket. In one implementation, the copula may be fitted as follows:

-   -   1. Feed factor return through its own CDF function to a         distribution of the grades; a uniformly distributed random         variable     -   2. Copula of a set of factors will be the joint distribution of         factors' grades. Joint=Copula+Marginals         For example, the SN R package may be utilized to determine the         copula and supports Gaussian, skewed Gaussian, T and Skewed T         Copula.

A multi-variate mixture model for the selected time period bucket may be trained at 485. For example, the multi-variate mixture model may be a multi-variate Gaussian mixture model. In one implementation, in Python, scipy.stats.multivariate_normal may be used for the different time period buckets to formulate a multi-variate Gaussian mixture. In another implementation, the SN R package may be utilized. In another implementation, training of the Gaussian mixture models may be implemented using Apache Spark. For example, the multi-variate mixture model for the selected time period bucket may be trained using the org.apache.spark.ml.clustering.GaussianMixture.fit( ) function, and the multi-variate mixture model may take the form of a org.apache.spark.ml.clustering.GaussianMixture multi-variate mixture datastructure. In one embodiment, the marginal distribution may be fitted to optimize the distributional families and their respective distributional parameters to minimize the KS test value between the marginal distribution and the historical distribution. In selecting various probability density functions such as Gaussian, skewed Gaussian, student T or skewed T copula, Cramer test and KS test values may be applied to minimize the multivariate and/or marginal distributions between simulated and historical data.

The number of market scenarios to simulate may be determined at 489. For example, 1,000 scenarios may be simulated (e.g., resulting in 60,000 total simulated scenarios over 60 time period buckets). In one implementation, the machine learning simulated scenario processing request may be parsed (e.g., using PHP commands) to determine the number of market scenarios to simulate for each of the time period buckets (e.g., based on the value of the number_of_simulated_market_scenarios field). In another implementation, the number of market scenarios to simulate for each of the time period buckets may be specified in a configuration setting. In another implementation, the number of market scenarios to simulate may differ for different time period buckets.

A determination may be made at 493 whether there remain market scenarios to simulate. If so, a set of simulated market factor changes may be generated using the multi-variate mixture model at 495. In one implementation, in Python, scipy.stats.multivariate_normal may be used to generate the set of simulated market factor changes. In another implementation, the SN R package may be utilized. In an alternative implementation, the set of simulated market factor changes may be generated using the scikit-learn sklearn.mixture.BayesianGaussianMixture.sample( ) method.

The simulated scenario may be stored in a database at 499. In one implementation, the simulated scenario may be stored (e.g., in a batch with other simulated scenarios) via a scenario results store request.

FIG. 5 shows a logic flow illustrating embodiments of a decision tree ensembles training (DTET) component for the MLPO. In FIG. 5, a decision tree ensembles training request may be obtained at 501. For example, the decision tree ensembles training request may be obtained as a result of an administrative user requesting training of decision tree ensembles.

Requested predictive capabilities may be determined at 505. For example, predictive capabilities may include estimating conditional Beta for a security, estimating conditional default for a security, and/or the like. In one implementation, the decision tree ensembles training request may be parsed (e.g., using PHP commands) to determine the requested predictive capabilities (e.g., based on the value of the predictive_capability_type fields). In another implementation, the requested predictive capabilities may be specified in a configuration setting.

A universe of securities to process may be determined at 509. For example, the universe of securities (e.g., securities in the S&P 500 Index) may include a list of equities, fixed income, and/or the like securities. In one implementation, the decision tree ensembles training request may be parsed (e.g., using PHP commands) to determine the universe of securities (e.g., based on the value of the universe_of_securities field). In another implementation, the universe of securities may be specified in a configuration setting.

A determination may be made at 513 whether there remain securities to process. In one implementation, each of the securities in the universe of securities may be processed. If there remain securities to process, the next security may be selected for processing at 517.

A determination may be made at 521 whether there remain predictive capabilities to train for the selected security. In one implementation, each of the requested predictive capabilities for the selected security may be trained. If there remain predictive capabilities to train, the next predictive capability may be selected for training at 525.

Features to use for training decision tree ensembles that provide the selected predictive capability for the selected security may be determined at 529. For example, different features may be used when training decision tree ensembles for fixed income and equity securities, for conditional Beta and conditional default. See FIGS. 6A-D for examples of features that may be used when training decision tree ensembles. In one implementation, the decision tree ensembles training request may be parsed (e.g., using PHP commands) to determine the features to use for training (e.g., based on the value of the training_features field). In another implementation, the features to use for training may be specified in a configuration setting.

A determination may be made at 533 whether sufficient training data is available for training decision tree ensembles that provide the selected predictive capability for the selected security. For example, if the features to use for training include pricing history features, a determination may be made if sufficient pricing history data for the selected security is available.

If sufficient training data is available for training decision tree ensembles that provide the selected predictive capability for the selected security, the training data may be obtained at 537. In one implementation, a reference to a training data datastructure may be obtained. For example, the training data datastructure may be structured as follows:

Target Feature_1_ID:Value Feature_2_ID:Value Feature_N_ID:Value (Beta) (cashmta) (ni_ta) . . . (sec45) Data Point 1 1.1 1:0.3 2:0.5 4:1 Data Point 2 1.4 1:0.2 2:0.6 4:0 . . . As an example of training data for a muni instrument for estimating Beta, the Beta of the instrument returns vs. muni index average return over a three month time period may be calculated using rolling 3 month daily returns. This set of Beta is the target variable. The market scenarios leading up to the return period are the trailing market scenario features. Instrument to index relative features are used to capture idiosyncratic risk (e.g., some muni instruments spread will trade richer, others cheaper relative to the muni index average spread). The market scenarios within the return period are also used as features.

A determination may be made at 541 whether a termination condition for training decision tree ensembles that provide the selected predictive capability for the selected security has been reached. In various implementations, the termination condition may comprise one or more of a specified number of training iterations, a specified training time, a specified minimum performance rank, and/or the like. For example, a performance rank may be determined by calculating R² for the decision tree ensembles (e.g., available data points may be split into 75% training data points and 25% testing data points for validation).

If the termination condition for training the decision tree ensembles has not been reached, a determination may be made at 545 whether there remain more training data points to use for training the decision tree ensembles. In one implementation, each of the training data points in the training data datastructure may be used for training. If there remain more training data points, the next training data point (e.g., Beta and feature values) may be selected at 549. The decision tree ensembles may be trained on the selected training data point using gradient boosting at 553. In one implementation, the XGBoost library may be used to train the decision tree ensembles using the training data datastructure. For example, in Python, using the XGBoost package, the decision tree ensembles may be trained as follows:

Training: def exe_xgb(ft_pd): data = ft_pd.copy( ) X = data.iloc[:, 1:] y = data.iloc[:, 0] X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25) model = xgb.XGBRegressor( ) model.fit(X_train, y_train) score = model.score(X test, y test) return model, score Scoring: def calculate_inst(x): key_cusip = x[0] ft_no_sim = x[1] model_cusip = x[2] Row_list =[ ] features_pd = ft_sim_pd_orig.copy( ) scoring_df = features_pd[features_pd.columns[:ft_sim_ini]] ft_row_num = len(features_pd) ft_left  = ft_no_sim.values * ft_row_num ft_left  = pd.DataFrame(ft_left, columns=list(ft_no_sim.columns)) ft_right = features_pd[features_pd.columns[ft_sim_ini:]] X_scoring = pd.concat([ft_left, ft_right], axis=1) y_scoring = model_cusip.predict(X_scoring) y_scoring = pd.DataFrame(y_scoring, columns=[‘measure_value’]) y_scoring[‘asset_id’]   = key_cusip y_scoring_complete = scoring_df.join(y_scoring) y_scoring_complete = y_scoring_complete[col_order] for index, rows in y_scoring_complete.iterrows( ): my_list =[int(rows.asset_id), int(rows.market_id), float(rows.measure_value)] Row_list.append(my_list) return Row_list

If the termination condition for training the decision tree ensembles has been reached, the trained decision tree ensembles that provide the selected predictive capability for the selected security may be stored in a database at 557. In one implementation, the decision tree ensembles may be stored via a decision tree ensembles store request.

FIGS. 6A-D show implementation case(s) for the MLPO. In FIGS. 6A-D, features that may be used for estimating conditional Beta and/or conditional default are illustrated.

FIG. 7A shows a logic flow illustrating embodiments of an expected returns calculation (ERC) component for the MLPO. In FIG. 7A, an expected returns calculation request may be obtained at 701. For example, the expected returns calculation request may be obtained as a result of an administrative user requesting calculation of expected returns for a universe of securities under simulated scenarios (e.g., of a simulation).

The universe of securities to process may be determined at 705. For example, the universe of securities (e.g., securities in the S&P 500 Index) may include a list of equities, fixed income, and/or the like securities. In one implementation, the expected returns calculation request may be parsed (e.g., using PHP commands) to determine the universe of securities (e.g., based on the value of the universe_of_securities field). In another implementation, the universe of securities may be specified in a configuration setting.

A determination may be made at 709 whether there remain securities to process. In one implementation, each of the securities in the universe of securities may be processed. If there remain securities to process, the next security may be selected for processing at 713.

Simulated market scenarios to analyze may be determined at 715. In one implementation, the expected returns calculation request may be parsed (e.g., using PHP commands) to determine the simulated market scenarios to analyze (e.g., based on the values of the simulation_identifier field and/or the simulated_scenarios field). In another implementation, the simulated market scenarios to analyze may be specified in a configuration setting.

A determination may be made at 717 whether there remain simulated market scenarios to analyze. In one implementation, each of the simulated market scenarios (e.g., of the simulation) may be analyzed. If there remain simulated market scenarios to analyze, the next market scenario (e.g., from the 60,000 simulated scenarios) may be selected for analysis at 721.

Features to utilize for conditional Beta estimation for the selected security under the selected simulated market scenario may be determined at 725. For example, different features may be used when estimating conditional Beta for fixed income and equity securities. In one implementation, the features that were used for training decision tree ensembles for estimating conditional Beta, as discussed with regard to FIG. 5, may be utilized. In one embodiment, the calculation of conditional Beta for different assets may be parallelized using Apache Spark. The mapper function may partition by asset_id, such as CUSIP, and may use XGBoost to train a model for each asset. The data frames for the XGBoost models may be stored as binary data as part of the calculation workflow to a relational database concurrently. The scoring process that generates a distribution of Beta for each asset may also be parallelized. The data storage design and parallel computing implementation of the MLPO allows each asset to have its own set of residuals. The residuals may be further analyzed to ensure that there is no systematic bias overstating or understating the simulated Beta, and/or that the residuals are not correlated with the simulated Beta. The sum of the simulated Beta from common risk factors and the residuals may be stored as the final simulated Beta. For example, the XGBoost model may be executed as follows:

model_function = generate_model(model_column, instrument_column, ratio_column, factor_column, delta_length, time_series_length, delta_name, feature_engineering_function_name, xgb_function_name) conditional_beta_model = raw_data.rdd \ .map(extract cusip)\ .groupByKey(num_partitions)\ .map(function_including_feature_engineering_and_xgb)

A determination may be made at 729 whether sufficient estimation data is available for estimating conditional Beta for the selected security under the selected simulated market scenario. In one implementation, a determination may be made whether instrument data for the selected security during the time period associated with the selected simulated market scenario is available. For example, if the features to use for conditional Beta estimation include pricing history features, a determination may be made if pricing history data for the selected security is available during the time period associated with the selected simulated market scenario. In another implementation, a determination may be made whether decision tree ensembles for estimating conditional Beta for the selected security exist. For example, if sufficient training data was not available, decision tree ensembles for estimating conditional Beta for the selected security may not have been trained.

If sufficient estimation data is available (e.g., decision tree ensembles exist and pricing history data is available), the selected security's conditional Beta may be estimated using the decision tree ensembles trained to estimate conditional Beta for the selected security at 733. In one implementation, the decision tree ensembles may be queried to predict the selected security's conditional Beta based on the estimation data.

If sufficient estimation data is not available (e.g., decision tree ensembles do not exist or pricing history data is not available), the selected security's conditional Beta may be estimated using a machine learning (ML) method at 737. In one implementation, the k-NN method may be used to estimate conditional Beta for the selected security by finding the closest modeled security to the selected security, and using the closest modeled security's estimated conditional Beta as a proxy of the selected security's estimated conditional Beta. For example, the features to utilize for conditional Beta estimation may be used as inputs to the k-NN to find the closest modeled security.

Features to utilize for conditional default probability estimation for the selected security under the selected simulated market scenario may be determined at 741. For example, different features may be used when estimating conditional default probability for fixed income and equity securities. In one implementation, the features that were used for training decision tree ensembles for estimating conditional default probability, as discussed with regard to FIG. 5, may be utilized.

A determination may be made at 745 whether sufficient estimation data is available for estimating conditional default probability for the selected security under the selected simulated market scenario. In one implementation, a determination may be made whether instrument data for the selected security during the time period associated with the selected simulated market scenario is available. For example, if the features to use for conditional default probability estimation include pricing history features, a determination may be made if pricing history data for the selected security is available during the time period associated with the selected simulated market scenario. In another implementation, a determination may be made whether decision tree ensembles for estimating conditional default probability for the selected security exist. For example, if sufficient training data was not available, decision tree ensembles for estimating conditional default probability for the selected security may not have been trained. In one embodiment, the calculation of default probability for different assets may be parallelized using Apache Spark. The mapper function may partition by asset_id, such as CUSIP, and may use XGBoost to train a model for each asset. Features, such as company financials data and macro factors, may be distributed by asset id. The data frames for the XGBoost models may be stored as binary data as part of the calculation workflow to a relational database concurrently. The scoring process that generates a default probability distribution for each asset under various simulated market scenarios may also be parallelized with factor simulation data broadcasted to the worker nodes. The data storage design and parallel computing implementation of the MLPO allows each instrument to have its own XGBoost model. For example, the XGBoost model may be executed as follows:

model_function = generate_model(model_column, instrument_column, ratio_column, factor_column, delta_length, time_series_length, delta_name, feature_engineering_function_name, xgb_function_name, sector_column, default_probability_column) conditional_default_model = raw_data.rdd \ .map(extract cusip)\ .groupByKey(num_partitions)\ .map(function_including_feature_engineering_and_xgb)

If sufficient estimation data is available (e.g., decision tree ensembles exist and pricing history data is available), the selected security's conditional default probability may be estimated using the decision tree ensembles trained to estimate conditional default probability for the selected security at 749. In one implementation, the decision tree ensembles may be queried to predict the selected security's conditional default probability based on the estimation data.

If sufficient estimation data is not available (e.g., decision tree ensembles do not exist or pricing history data is not available), the selected security's conditional default probability may be estimated using a machine learning (ML) method at 753. In one implementation, the k-NN method may be used to estimate conditional default probability for the selected security by finding the closest modeled security to the selected security, and using the closest modeled security's estimated conditional default probability as a proxy of the selected security's estimated conditional default probability. For example, the features to utilize for conditional default probability estimation may be used as inputs to the k-NN to find the closest modeled security.

Default for the selected security under the selected simulated market scenario may be simulated at 757. In one implementation, the value of a random variable that has values corresponding to Default (e.g., with probability equal to: the selected security's conditional default probability) and No Default (e.g., with probability equal to: 1—the selected security's conditional default probability) expected return types may be simulated. For example, the value of the random variable may be randomly generated from a standard normal distribution as a number from 0 to 1. If the number is smaller than the estimated conditional default probability, the default value is set to 1 (Default), otherwise to 0 (No Default) (e.g., if the conditional default probability for market scenario 10001 is 10% and the randomly generated number is 0.312, then the asset's default flag for scenario 10001 is set to 0 (No Default); if the randomly generated number is 0.05, which is smaller than 0.1 (10% default probability), then the asset's default flag for scenario 10001 is set to 1 (Default)).

A determination may be made at 761 whether the expected return type for the selected security under the selected simulated market scenario is Default or No Default. If the expected return type is No Default, an expected return for the selected security under the selected simulated market scenario may be calculated at 765. For example, the expected return (ER) may be calculated as follows:

Fixed Income Assets—No Default:

${ER} = {{\sum\limits_{{factor} = 1}^{n}\;{{{Exposure}\left( {f,i} \right)} \times {Conditional}\mspace{14mu}{{Beta}\left( {i,m} \right)} \times {Simulated}\mspace{14mu}{Factor}\mspace{14mu}{{Change}\left( {f,m} \right)}}} + {Carry} + {Rolldown}}$

Equity Assets—No Default:

ER=Conditional Beta(i,m)×Simulated Return of Equity Index(f,m)

Where:

-   -   f is the number of market factors for which an instrument has         price sensitivities     -   i is the number of instruments in the investable universe     -   Exposure is a f by i matrix that contains instruments' return         sensitivities to market factors. They are calculated as the Beta         of instruments' return to the market factor change. For example,         for fixed income instruments, the exposure to interest rate risk         factors may be option adjusted durations. They may be calculated         by moving the rates up and down “shocking the yield curve”,         discounting the cashflows of the bond while adjusting for         optionality. The bigger the differences in present values for a         given unit of interest rate shock, the higher the duration, aka         “return sensitivity to rates”.     -   m is the number of simulated market scenarios     -   For example, each instrument i may have a different Beta along         each simulated market scenario     -   Conditional Beta is a i by m matrix     -   Simulated Factor Change is a f by m matrix; each market factor         may have a simulated change value along each market scenario     -   Equity Index is a market factor simulated along with other         market factors     -   Conditional beta may be calculated for individual equities         against their respective equity indices for each simulated         market scenario.

If the expected return type is Default, an expected return for the selected security under the selected simulated market scenario may be calculated at 769. For example, the expected return (ER) may be calculated as follows:

Fixed Income Assets—Default:

${ER} = \frac{\left( {\left( {{Recovery}\mspace{14mu}{Rate} \times 100} \right) - {Price}} \right)}{Price}$

Equity Assets—Default:

ER = 0 Where: ${{Recovery}\mspace{14mu}{Rate}} = {1 - \frac{{Credit}\mspace{14mu}{Spread}}{{Conditional}\mspace{14mu}{Default}\mspace{14mu}{Probability}}}$

The calculated expected returns may be stored in a database at 773. In one implementation, the calculated expected returns may be stored via an expected returns store request.

FIG. 7B illustrates embodiments of a computation engine architecture that supports and implements the business logic. In various implementations the computation engine may be characterized by the following features:

1: Parallel on Parallel Hierarchy and Flexible Calculation Dependencies: Use Apache AirFlow to define calculation workflow and enable concurrent processing of a single or multiple calculation module(s) and flexible dependencies. For example, 3 month, 6 month and 12 months (e.g., based on rolling window period length) simulations from multiple factor simulation models may be processed in parallel. The dependency management allows risk data maintenance and pushing risk analytics to a cloud based datamart (e.g., SnowFlake) upon the completion of asset return simulation for assets across time horizons and simulation models. Furthermore, within each calculation module, Apache Spark may be used to enable parallel computing of instruments. For example, to calculate 12 month asset return simulation for the deep learning model (asim1Y_DL_CMA), over 130,000 bond instruments may be distributed across hundreds of worker nodes in the cloud. This type of parallel on top of parallel technology approach maximizes the utilization of cloud based computing power and provides control and flexibility for defining calculation dependencies.

2: Self-Service: Computation capabilities may be authored by domain experts. Team members may orchestrate and assemble the capabilities and declare dependencies with custom built WDL (Workflow Declaration Language). In one implementation, YAML may be used as the WDL.

3: Heterogenous Platforms: Various computation platforms such as parallel computing using Apache Spark using Scala/Java/Python, distributed computing on Virtual Servers using Golang, SQL and shell scripts, and/or the like may be supported.

4: Event-Based: Tasks in the Workflow may be automatically triggered based on events.

5: Cloud provider Agnostic: Open source technologies such as Apache Airflow, Apache Spark and Postgresql, and/or the like may be leveraged.

6: Performance Optimization: Computation performance may be optimized by using network-optimized, memory-optimized and/or compute-optimized cloud instances based on the nature of the computation. Multiple jobs may be scheduled to single or multiple clusters.

The visual view of the above workflow is illustrated at 702 in FIG. 7C.

Exemplary pseudo code that distributes the asset simulation across provisioned clusters of nodes is shown below. Exposure data in ‘expo’ and factor simulation data (encapsulated in the curried function fsim_func) may be broadcasted to the worker nodes for distributed computation.

Expo data are read and partitioned by asset_id: expo_tall_sdf = self.sqlContext.read.jdbc( url=self.jdbc_conn_str, table=fexpo_sql, properties=conn_props ) partition_meta = { ‘numPartitions': str(self.read_partitions), ‘partitioncolumn’: ‘ asset_id’, ‘lowerBound’: ‘0’, ‘upperBound’: str(self.select_fexpo_count(pricing_dt)) } expo.rdd.map(fsim_func)

Calculations may be executed concurrently on the worker nodes using pseudo code such as shown below. Factor Sims may be broadcasted to the worker nodes.

def calculate_inst(x): “‘’” Performs dot product between row of Factor Exposer RDD (x) and Factor Sim matrix return as list of lists. “‘’” sy = asset_ref_dict.get(str(x.asset_id), { }).get(“static_yield”, Decimal(‘0.0’)) # month to mature mon2mature = asset_ref_dict.get(str(x.asset_id), { }).get(“month_to_mature”, { }) bias_coef = bias_coef_with_month2mature(mon2mature, horizon) # Dot product and set datatype as float fsim = fsim_vals.astype(float) fexpo = np.array(x)[fexpo_fctr_idx].astype(float) return_arry = fsim.dot(fexpo) # clip return via option price upper and lower p_lower = asset_ref_dict.get(str(x.asset_id), { }).get(“price_lower”, { }) p_upper = asset_ref_dict.get(str(x.asset_id), { }).get(“price_upper”, { }) return_clip = clip_lower_and_upper(p_lower, p_upper, return_arry) # add carry return_clip_plus_carry = np.array(return_clip).astype(float) + float(bias_coef) * float(sy) # CVaR calculation cvar_minus = np.mean(np.sort(return_clip_plus_carry)[:int(len(return_clip_plus_carry) * cvar_percentile * 0.01)]) return_int = array2int(return_clip_plus_carry) return [x.asset_id, x.pricing_dt, sim_id, return_int, float(cvar_minus)]

The generated asset simulation data may be populated into RDMS Postgresql and Enterprise Snowflake Data Lake in a wide format for optimal performance. The wide format is illustrated at 706 in FIG. 7C.

The wide format may be turned into a tall format for reporting and analysis as follows:

SELECT asset_id, sim_id, generate_series(0,7449) market_id, unnest(returns) as returns FROM prod.asset_sim_w WHERE asset_id=2012082100000122 and sim_id=34 and pricing_dt=‘2020-06-05’ ORDER BY 1,2,3;

The tall format is illustrated at 710 in FIG. 7C. In this figure, market scenario identifier field scenario_identifier is referred to as market_id.

A portfolio constructing (PC) component 833 may utilize data provided in the portfolio construction request and/or the expected returns retrieve response and/or via filters to determine and/or execute a set of tradeable buy and/or sell transactions to construct an optimized portfolio. See FIG. 9 for additional details regarding the PC component.

The MLPO server 806 may send an order execution request 837 to an exchange server 808 to facilitate executing a tradeable buy and/or sell transaction used to construct the optimized portfolio. In one implementation, the order execution request may include data such as a request identifier, order details, and/or the like.

FIG. 9 shows a logic flow illustrating embodiments of a portfolio constructing (PC) component for the MLPO. In FIG. 9, a portfolio construction request may be obtained at 901.

For example, the optimization parameters may include a universe of investment securities, investment amount, Conditional Value at Risk (CVaR) percentile, CVaR threshold, an investment time period, whether to optimize relative to a benchmark portfolio, benchmark portfolio weights, integer quantity constraint, and/or the like. In one implementation, the portfolio construction request may be parsed (e.g., using PHP commands) to determine the optimization parameters (e.g., based on the value of the optimization_parameters field). For example, the optimization parameters may be specified as follows:

Market scenarios to utilize for constructing the optimized portfolio may be determined at 907. In one embodiment, the market scenarios to utilize may be determined based on the simulation model (e.g., for a specified pricing date) and/or time period length selected by the user. For example, the user may choose to utilize simulated market scenarios generated using a deep learning neural network simulation model (e.g., for the specified pricing date) for a 3 month, 6 month or 1 year investment time period (e.g., as discussed with regard to FIGS. 2A-B), or to utilize simulated market scenarios generated using a multivariate mixture simulation model (e.g., for the specified pricing date) for a 3 month, 6 month or 1 year investment time period (e.g., as discussed with regard to FIG. 4). In another embodiment, the market scenarios to utilize may be determined based on filters applied to simulated market scenarios. For example, the user may choose to filter simulated market scenarios based on specified ranges of allowable values for specified customized market factors (e.g., as discussed with regard to FIG. 21), and/or based on specified business cycle settings (e.g., as discussed with regard to FIG. 27).

Expected returns of securities in the universe of investment securities for the determined market scenarios to utilize may be retrieved from a database at 909. For example, if the user wishes to construct an optimized portfolio for a 6 month investment time period using a deep learning neural network simulation model, expected returns of securities in the universe of investment securities for simulated market scenarios generated by the deep learning neural network simulation model for 6 month rolling window periods (e.g., for the 60,000 simulated scenarios) may be retrieved. In another example, if the user wishes to construct an optimized portfolio conditional on VIX rising more than 400 bps over a 3 month horizon, expected returns of securities in the universe of investment securities for filtered simulated market scenarios having VIX change greater than 400 bps over the 3 month horizon may be retrieved. In another example, if the user wishes to construct an optimized portfolio conditional on having Late business cycle over a 3 month horizon, expected returns of securities in the universe of investment securities for filtered simulated market scenarios associated with Late business cycle over the 3 month horizon may be retrieved (e.g., alternatively, weighted expected security returns may be utilized when multiple business cycles with associated business cycle weights are utilized). In one implementation, the expected returns may be retrieved via an expected returns retrieve request.

A determination may be made at 913 whether the optimized portfolio should be optimized relative to a benchmark portfolio. If so, starting securities weights may be initialized to benchmark portfolio weights at 917.

Portfolio securities weights may be optimized in accordance with the optimization parameters at 921. In one implementation, the PC component may perform a convex optimization to find a mixed integer linear programming (MILP) portfolio solution that ensures that tradable buy and sell transactions can be generated. The optimization objective may be set to maximize the expected portfolio return. In various embodiments, a variety of approaches may be used to perform the optimization. For example, one approach is to use stochastic optimization process to search for suboptimal weights of the asset for a fixed amount of time and/or iterations and select the solution with allowable CVaR and maximum returns. For example, a second approach is to use MILP to solve for the global optimum solution and use linear relaxation of CVaR constraint with the weights result in tradability for each security respecting the trading rules such as minimum denomination and minimum increments. For example, a third approach is to use linear relaxation of CVaR constraint, but use a binary branch and cut modified MILP implementation (BILP), where non-integer solutions are allowed for those bigger than the minimum denomination values. For example, a fourth approach is to use linear relaxation of CVaR constrain and conduct a direct linear programing optimization, allowing the allocated weights to be a non-integer (decimal) solution and rounding the trade quantity to the nearable tradable amount. In one embodiment, the optimization implementation may be solver independent. In various implementations, multiple linear programming, quadratic programming and mixed integer programming solvers may be supported, including both commercial solvers and open-source solvers (e.g., CVXOPT(SIMPLEX), GUROBI, scypy.optimize(interior point)). For example, the user may select which solvers to use from a portfolio construction graphical user interface.

Tradeable buy and/or sell transactions to execute may be determined at 925. In one embodiment, the tradeable buy and/or sell transactions are generated to make weights of securities in the optimized portfolio correspond to the determined optimized portfolio securities weights. In one implementation, the optimized portfolio may be a newly created portfolio. For example, tradeable buy transactions may be determined to obtain each security with a non-zero weight in accordance with its optimized portfolio weight. In another implementation, the optimized portfolio may be an existing portfolio (e.g., the benchmark portfolio). For example, tradeable buy and/or sell transactions may be determined to increase and/or reduce weights of securities in the existing portfolio to make the weight of each security correspond to its optimized portfolio weight.

The tradeable buy and/or sell transactions may be executed at 929. In one implementation, orders corresponding the tradeable buy and/or sell transactions may be sent to an exchange server via one or more order execution requests.

The user may utilize a CVaR threshold widget 1110 to specify the expected loss (e.g., 7%) at the worst CVaR percentile outcomes (e.g., the expected loss based on a weighted average (e.g., weighted based on occurrence probability) of the worst 5% of return outcomes). The user may utilize an investment time period widget 1115 to specify the investment time frame (e.g., over a 3 month time period). The user may utilize optimization objective widgets 1120, 1125 to specify the optimization objective (e.g., maximize total return). Other portfolio construction constraints that may be specified by the user may include: maximum percentage market value (PMV) per allocated asset, minimum number of allocated assets per portfolio, and/or the like. The user may utilize an optimize widget 1130 to initiate the creation of the optimized portfolio.

In FIG. 12, an exemplary user interface (e.g., for a mobile device, for a website) for constructing an optimized portfolio is illustrated. Screen 1201 shows exemplary values that the user may select using the CVaR percentile widget 1205, the CVaR threshold widget 1210, and the investment time period widget 1215. The user may utilize an expected return widget 1220 to view the expected return (e.g., −6.61%) of the optimized portfolio, the expected return (e.g., 0.81%) of the original portfolio before changes to the portfolio securities weights, and the difference in the expected return (e.g., −7.43%) between the two portfolios. The user may utilize a drawdown widget 1225 to view the expected loss (e.g., −7.00%) at the worst CVaR percentile outcomes for the optimized portfolio, the expected loss (e.g., −8.35%) at the worst CVaR percentile outcomes for the original portfolio before changes to the portfolio securities weights, and the difference in the expected loss at the worst CVaR percentile outcomes (e.g., 1.35) between the two portfolios. The user may utilize a return volatility widget 1230 to view the return volatility (e.g., 3.62%) of the optimized portfolio, the return volatility (e.g., 3.80%) of the original portfolio before changes to the portfolio securities weights, and the difference in the return volatility (e.g., −0.19%) between the two portfolios.

A predefined scenario constructing (PSC) component 1333 may utilize data provided in the predefined scenario construction request, data provided in the scenario results retrieve response, and/or data provided via scenario customization input to construct the predefined scenario. See FIGS. 14A-B for additional details regarding the PSC component.

The user client 1304 may send a scenario customization input 1337 to the MLPO server 1306 to specify a range of values for a customized market factor. In some alternative embodiments, the scenario customization input may instead be sent by the administrative client 1302. In one implementation, the scenario customization input may include data such as a request identifier, a market factor identifier, a minimum range value, a maximum range value, and/or the like. In one embodiment, the user client may provide the following example scenario customization input, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

The MLPO server 1306 may send a scenario customization output 1341 to the user client 1304 to inform the user how ranges of values for other market factors have been affected by the change to the customized market factor. In some alternative embodiments, the scenario customization output may instead be sent to the administrative client 1302. In one implementation, the scenario customization output may include data such as a response identifier, ranges of values for market factors, and/or the like. In one embodiment, the MLPO server may provide the following example scenario customization output, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

The MLPO server 1306 may send a predefined scenario store request 1345 to the repository 1310 to facilitate storing the constructed predefined scenario. In one implementation, the predefined scenario may be stored as a set of customized market factors and specified ranges of values for customized market factors in the set, and the predefined scenario store request may include data such as a request identifier, a user identifier, a predefined scenario identifier, a simulation model, a pricing date, ranges of values for market factors, and/or the like. In one embodiment, the MLPO server may provide the following example predefined scenario store request, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /predefined_scenario_store_request.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <predefined_scenario_store_request> <request_identifier>ID_request_24</request_identifier> <user_identifier>ID_user_1</user_identifier> <predefined_scenario_identifier> ID_predefined_scenario_1 </predefined_scenario_identifier> <simulation_model>ID_neural_network_simulation_model_1Y</simulation_model> <pricing_date>2020-04-17</pricing_date> <customized_market_factors> <customized_market_factor> <market_factor_identifier>ID_oil_price</market_factor_identifier> <minimum_range_value>−49.00</minimum_range_value> <maximum_range_value>19992.00</maximum_range_value> <average_range_value>2698.92</average_range_value> </customized_market_factor> <customized_market_factor> <market_factor_identifier>ID_interest_rate_6M</market_factor_identifier> <minimum_range_value>40.00</minimum_range_value> <maximum_range_value>333.00</maximum_range_vaiue> <average_range_value>132.76</average_range_value> </customized_market_factor> </customized_market_factors> </predefined_scenario_store_request>

In another implementation, the predefined scenario may be stored as a set of simulated market scenarios that satisfy specified ranges of values for customized market factors, and the predefined scenario store request may include data such as a request identifier, a user identifier, a predefined scenario identifier, a simulation identifier, a set of simulated market scenarios (e.g., filtered), and/or the like. In one embodiment, the MLPO server may provide the following example predefined scenario store request, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /predefined_scenario_store_request.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <predefined_scenario_store_request> <request_identifier>ID_request_24</request_identifier> <user_identifier>ID_user_1</user_identifier> <predefined_scenario_identifier> ID_predefined_scenario_1 </predefined_scenario_identifier> <simulation_identifier>ID_sim_1</simulation_identifier> <scenario_identifiers>ID_scenario_1, ID_scenario_2, ...</scenario_identifiers> </predefined_scenario_store_request>

The repository 1310 may send a predefined scenario store response 1349 to the MLPO server 1306 to confirm that the constructed predefined scenario was stored successfully. In one implementation, the predefined scenario store response may include data such as a response identifier, a status, and/or the like. In one embodiment, the repository may provide the following example predefined scenario store response, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /predefined_scenario_store_response.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <predefined_scenario_store_response> <response_identifier>ID_response_24</response_identifier> <status>OK</status> </predefined_scenario_store_response>

The MLPO server 1306 may send a predefined scenario construction response 1353 to the user client 1304 to inform the user that the constructed predefined scenario was stored successfully. In some alternative embodiments, the predefined scenario construction response may instead be sent to the administrative client 1302. In one implementation, the predefined scenario construction response may include data such as a response identifier, a status, and/or the like. In one embodiment, the MLPO server may provide the following example predefined scenario construction response, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /predefined_scenario_construction_response.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <predefined_scenario_construction_response> <response_identifier>ID_response_21</response_identifier> <status>OK</status> </predefined_scenario_construction_response>

FIGS. 14A-B show a logic flow illustrating embodiments of a predefined scenario constructing (PSC) component for the MLPO. In FIG. 14A, a predefined scenario construction request may be obtained at 1401. For example, the predefined scenario construction request may be obtained as a result of a user requesting construction of a predefined scenario.

Market scenarios to utilize for constructing the predefined scenario may be determined at 1405. In one embodiment, the market scenarios to utilize may be determined based on the simulation model (e.g., for a specified pricing date) and/or time period length selected by the user. In another embodiment, the market scenarios to utilize may be determined based on filters applied to simulated market scenarios. In one implementation, the predefined scenario construction request may be parsed (e.g., using PHP commands) to determine the market scenarios to utilize (e.g., based on the values of the simulation_model and/or pricing_date fields). For example, the selected simulation model and/or pricing date may be used to determine a simulation identifier (e.g., ID_sim_1) of the corresponding simulation (e.g., a set of simulated market scenarios).

The market scenarios to utilize may be retrieved from a database at 1409. In one implementation, the market scenarios to utilize may be retrieved via a scenario results retrieve request.

Market factors to process may be determined at 1413. For example, market factors may include interest rates, credit spread, oil price, equity indices, and/or the like. In one implementation, the market factors to process may be determined based on market factors utilized in the simulation. For example, the market factors to process may be determined via a MySQL database command similar to the following:

SELECT scenarioMarketFactorID FROM ScenarioResults WHERE simulationID = ID_sim_1;

In another implementation, a set of default market factors to process may be specified in a configuration setting.

A determination may be made at 1417 whether there remain market factors to process. In one implementation, each of the market factors may be processed. If there remain market factors to process, the next market factor (e.g., 6 month change in oil price) may be selected for processing at 1421.

A factor group for the selected market factor may be determined at 1425. In one embodiment, market factors may be organized into factor groups to facilitate searching for market factors by the user. For example, the change in oil prices market factor may be associated with the Macro factor group. In one implementation, the factor group associated with each market factor may be specified in a configuration setting. In some implementations, multiple factor groups may be associated with a market factor.

A range of market factor values for the selected market factor may be determined at 1429. For example, the range may include a minimum market factor value, a maximum market factor value, an average market factor value, and/or the like for the market scenarios to utilize. In one implementation, the range of market factor values for each market factor may be precalculated. For example, the range of market factor values for the selected market factor may be determined via a MySQL database command similar to the following:

SELECT simulationMarketFactorRangeMin, simulationMarketFactorRangeMax, simulationMarketFactorRangeAverage FROM ScenarioResults WHERE simulationID = ID_sim_1 AND scenarioMarketFactorID = ID_oil_price;

In another implementation, the range of market factor values for each market factor may be determined by iterating through the market scenarios to utilize and calculating the range based on the market factor values for the market scenarios to utilize. For example, the range of market factor values for the selected market factor may be determined via a MySQL database command similar to the following:

SELECT MIN(scenarioSimulatedMarketFactorChange), MAX(scenarioSimulatedMarketFactorChange), AVG(scenarioSimulatedMarketFactorChange) FROM ScenarioResults WHERE simulationID = ID_sim_1 AND scenarioMarketFactorID = ID_oil_price;

A set of customized market factors may be determined at 1433. For example, a market factor may be customized by specifying a subrange of allowable values for the market factor. In one embodiment, the user may utilize a user interface widget to create a new predefined scenario (e.g., with no customized market factors). In another embodiment, the user may utilize a user interface widget to select an existing predefined scenario with a set of customized market factors. In one implementation, the set of customized market factors for a predefined scenario (e.g., with identifier ID_predefined_scenario_1) may be retrieved from a database. For example, the set of customized market factors for the predefined scenario may be determined via a MySQL database command similar to the following:

SELECT customizedMarketFactorID FROM PredefinedScenarios WHERE predefinedScenarioID = ID_predefined_scenario_1;

The market scenarios to utilize may be filtered based on the set of customized market factors at 1437. In one embodiment, the market scenarios to utilize may be filtered to the subset of market scenarios that satisfy the subrange of allowable values for each customized market factor. See FIG. 14B for additional details regarding filtering the market scenarios to utilize based on customized market factors.

A determination may be made at 1441 whether there remain market factors to process. In one implementation, each of the market factors may be processed to determine ranges for the filtered market scenarios. If there remain market factors to process, the next market factor (e.g., 6 month change in oil price) may be selected for processing at 1445.

A determination may be made at 1449 whether there remain filtered market scenarios to analyze. In one implementation, each of the filtered market scenarios may be analyzed. If there remain filtered market scenarios to analyze, the next filtered market scenario (e.g., with identifier ID_scenario_1) may be selected for analysis at 1453.

A market factor value of the selected market factor for the selected filtered market scenario may be determined at 1457. In one implementation, the market factor value may be retrieved from a database. For example, the market factor value of the selected market factor for the selected market scenario may be determined via a MySQL database command similar to the following:

SELECT scenarioSimulatedMarketFactorChange FROM ScenarioResults WHERE simulationID = ID_sim_1 AND scenarioID = ID_scenario_1 AND scenarioMarketFactorID = ID_oil_price;

The determined market factor values may be analyzed to determine a range of filtered market factor values for the selected market factor at 1461. For example, the range may include a minimum market factor value, a maximum market factor value, an average market factor value, and/or the like for the filtered market scenarios.

A visualization of the market factors may be generated at 1465. In one embodiment, the visualization may show the range of unfiltered market factor values and/or the range of filtered market factor values for each of the market factors. In one implementation, a user interface widget may be generated for each of the market factors showing the range of unfiltered market factor values and/or the range of filtered market factor values for the respective market factor. See FIGS. 15-19 for examples of visualizations that may be generated.

A determination may be made at 1469 whether a scenario customization input was obtained from the user. In one embodiment, the scenario customization input may be a user interface input from the user with a user-specified range of allowable values for an updated market factor. If a scenario customization input was obtained, the specified range of allowable values for the updated market factor may be determined at 1473. For example, the user may specify an updated subrange of allowable values for a customized market factor (e.g., an existing customized market factor, a newly customized market factor). In another example, the user may specify that a previously customized market factor should no longer be customized (e.g., by updating the subrange of allowable values to the full range for the previously customized market factor). In one implementation, the scenario customization input may be parsed (e.g., using PHP commands) to determine the specified range of allowable values for the updated market factor (e.g., based on the values of the market_factor_identifier, minimum_range_value, and/or maximum_range_value fields). The set of customized market factors may be updated at 1477. In one embodiment, a newly customized market factor may be added to the set of customized market factors. In another embodiment, a previously customized market factor may be removed from the set of customized market factors. In one implementation, a list (e.g., an array of market factor identifiers, a map of market factor identifier values to customized status Boolean values) of customized market factors may be updated. The market scenarios to utilize may be filtered based on the updated set of customized market factors and an updated visualization of the market factors may be generated as discussed with regard to 1437-1465.

A determination may be made at 1481 whether a scenario save input was obtained from the user. In one embodiment, the scenario save input may be a user interface input from the user indicating that the predefined scenario should be saved. If a scenario save input was obtained, the predefined scenario may be stored at 1485. In one implementation, the predefined scenario may be stored via a predefined scenario store request.

FIG. 14B shows additional details regarding filtering the market scenarios to utilize based on customized market factors. In FIG. 14B, filtered market scenarios (e.g., an array of filtered market scenario identifiers, a map of market scenario identifier values to filtered status Boolean values) may be set to the market scenarios to utilize at 1402 (e.g., to clear any previously set filters).

A determination may be made at 1406 whether there remain customized market factors to process. In one implementation, each of the market factors in the set of customized market factors may be processed. If there remain customized market factors to process, the next customized market factor may be selected for processing at 1410.

The specified range of allowable values for the selected customized market factor may be determined at 1414. For example, the specified range of allowable values may include a minimum value and a maximum value. In one implementation, the specified range of allowable values for the selected customized market factor may be determined as discussed with regard to 1473 (e.g., for a new user-specified range). In another implementation, the specified range of allowable values for the selected customized market factor may be retrieved from a database (e.g., for an existing predefined scenario). For example, the specified range of allowable values for the selected customized market factor may be determined via a MySQL database command similar to the following:

SELECT customizedMarketFactorRangeMin, customizedMarketFactorRangeMax FROM PredefinedScenarios WHERE predefinedScenarioID = ID_predefined_scenario_1;

A determination may be made at 1418 whether there remain filtered market scenarios to analyze. In one implementation, each of the market scenarios that have not been removed from the filtered market scenarios (e.g., during processing of previously processed customized market factors) may be analyzed. If there remain filtered market scenarios to analyze, the next filtered market scenario may be selected for analysis at 1422.

A market factor value of the selected customized market factor for the selected filtered market scenario may be determined at 1426. In one implementation, the market factor value may be retrieved from a database. For example, the market factor value of the selected customized market factor for the selected filtered market scenario may be determined via a MySQL database command similar to the following:

SELECT scenarioSimulatedMarketFactorChange FROM ScenarioResults WHERE simulationID = ID_sim_1 AND scenarioID = ID_scenario_1 AND scenarioMarketFactorID = ID_oil_price;

A determination may be made at 1430 whether the determined market factor value is in the specified range of allowable values for the selected customized market factor. If the determined market factor value is outside the specified range of allowable values for the selected customized market factor, the selected filtered market scenario may be removed from the filtered market scenarios at 1434.

Once the customized market factors have been processed, the remaining filtered market scenarios may be returned at 1438. In one embodiment, the returned filtered market scenarios are market scenarios having market factor values that fall within the subrange of allowable values for each of the market factors in the set of customized market factors.

FIG. 15 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 15, an exemplary user interface (e.g., for a mobile device, for a website) for constructing a predefined scenario is illustrated. Screen 1501 shows that a user may utilize a load predefined scenario widget 1505 to select an existing predefined scenario (e.g., from predefined scenarios associated with the user's user identifier). The user may utilize an add new predefined scenario widget 1510 to create a new predefined scenario.

The user may utilize a pricing date widget 1515 and/or a simulation model widget 1520 to specify market scenarios to utilize. The user may search through market factors associated with the market scenarios to utilize by filtering displayed market factors using factor group filter widgets (e.g., 1525A-D). For example, utilizing All factor group widget 1525A may show unfiltered market factors associated with the market scenarios to utilize. In another example, utilizing Macro factor group widget 1525D may filter market factors to show market factors associated with the Macro factor group (e.g., change in oil price). The user may search through market factors associated with the market scenarios to utilize by filtering displayed market factors by market factor name using search by factor name widget 1527.

The user may view and/or modify ranges of allowable values for each market factor using market factor widgets (e.g., 1530A-C). For example, screen 1501 shows that ranges of allowable values for the market factors have not been modified (e.g., there are no customized market factors).

FIG. 16 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 16, an exemplary user interface (e.g., for a mobile device, for a website) for constructing a predefined scenario is illustrated. Screen 1601 shows that the user may modify ranges of allowable values for market factors of a predefined scenario (e.g., an existing predefined scenario selected using the load predefined scenario widget 1605, a new predefined scenario created using the add new predefined scenario widget 1610) using allowable range widgets (e.g., 1635A-C). Screen 1601 shows that when the user modifies the range of allowable values for a market factor, an updated visualization showing how ranges of allowable values for the market factors have been affected may be generated. For example, if the user modifies (e.g., using widget 1635B) the range of allowable values for the 6 month interest rate market factor (e.g., shown in widget 1630B (e.g., rearranged in order and/or highlighted to indicate a customized market factor)), an updated visualization showing how the range of allowable values (e.g., shown in widget 1635A) for the 3 month interest rate market factor (e.g., shown in widget 1630A) and how the range of allowable values (e.g., shown in widget 1635C) for the 1 year interest rate market factor (e.g., shown in widget 1630C) have changed based on the user-specified scenario customization input may be generated.

FIG. 17 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 17, an exemplary user interface (e.g., for a mobile device, for a website) for constructing a predefined scenario is illustrated. Screen 1701 shows that the user may utilize the Macro factor group widget 1725D to view how the ranges of allowable values (e.g., shown in widgets 1735D-F) for market factors associated with the Macro factor group (e.g., shown in widget 1730D-F) have changed based on the user-specified scenario customization input.

FIG. 18 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 18, an exemplary user interface (e.g., for a mobile device, for a website) for constructing a predefined scenario is illustrated. Screen 1801 shows that when the user modifies the range of allowable values for another market factor (e.g., associated with the Macro factor group), an updated visualization showing how ranges of allowable values for the market factors have been affected (e.g., based on both modifications) may be generated. For example, if the user modifies (e.g., using widget 1835D) the range of allowable values for the oil price market factor (e.g., shown in widget 1830D (e.g., rearranged in order and/or highlighted to indicate a customized market factor)), an updated visualization showing how the range of allowable values (e.g., shown in widget 1835E) for the VIX market factor (e.g., shown in widget 1830E) and how the range of allowable values (e.g., shown in widget 1835F) for the Commodities market factor (e.g., shown in widget 1830F) have changed based on the two user-specified scenario customization inputs may be generated.

FIG. 19 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 19, an exemplary user interface (e.g., for a mobile device, for a website) for constructing a predefined scenario is illustrated. Screen 1901 shows that the user may utilize the All factor group widget 1925A to view how the ranges of allowable values for the market factors have changed based on the user-specified scenario customization inputs. For example, market factor widget 1930A shows how the range of allowable values (e.g., shown in widget 1935A) for the 3 month interest rate market factor has changed based on the user-specified changes to the range of allowable values (e.g., shown in widget 1935B) for the 6 month interest rate market factor (e.g., shown in widget 1930B) and to the range of allowable values (e.g., shown in widget 1935D) for the oil price market factor (e.g., shown in widget 1930D). The user may save the predefined scenario using a save widget 1940.

FIG. 20 shows a datagraph illustrating data flow(s) for the MLPO. In FIG. 20, dashed lines indicate data flow elements that may be more likely to be optional. In FIG. 20, a user client 2004 (e.g., of a user) may send a portfolio returns visualization request 2021 to a MLPO server 2006 to facilitate generating a portfolio returns visualization based on customized market factors. For example, the user client may be a desktop, a laptop, a tablet, a smartphone, a smartwatch, and/or the like that is executing a client application.

A scenario based portfolio returns visualizing (SPRV) component 2033 may utilize data provided in the portfolio returns visualization request to generate a portfolio return metrics visualization. See FIG. 21 for additional details regarding the SPRV component.

The MLPO server 2006 may send a portfolio returns visualization response 2037 to the user client 2004 to provide a visualization of portfolio return metrics for the specified portfolio under the specified predefined scenario. In one implementation, the portfolio returns visualization response may include data such as a response identifier, visualization data, and/or the like. In one embodiment, the MLPO server may provide the following example portfolio returns visualization response, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /portfolio_returns_visualization_response.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <portfolio_returns_visualization_response> <response_identifier>ID_response_31</response_identifier> <visualization_data> portfolio return metrics data (e.g., constituent securities' and/or portfolio's returns, worst returns, return volatility, frequency vs. returns data) </visualization_data> </portfolio_returns_visualization_response>

If the user customizes a market factor, the user client 2004 may send a visualization scenario customization input 2041 to the MLPO server 2006 specifying a range of values for the customized market factor (e.g., to modify the predefined scenario). In one implementation, the visualization scenario customization input may include data such as a request identifier, a market factor identifier, a minimum range value, a maximum range value, and/or the like. In one embodiment, the user client may provide the following example visualization scenario customization input, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /visualization_scenario_customization_input.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <visualization_scenario_customization_input> <request_identifier>ID_request_34</request_identifier> <market_factor_identifier>ID_VIX</market_factor_identifier> <minimum_range_value>913.00</minimum_range_value> <maximum_range_value>5141.00</maximum_range_value> </visualization_scenario_customization_input>

The MLPO server 2006 may send a visualization scenario customization output 2045 to the user client 2004 to provide an updated visualization of portfolio return metrics for the specified portfolio (e.g., under the modified predefined scenario). In one implementation, the visualization scenario customization output may include data such as a response identifier, visualization data, and/or the like. In one embodiment, the MLPO server may provide the following example visualization scenario customization output, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

POST /visualization_scenario_customization_output.php HTTP/1.1 Host: www.server.com Content-Type: Application/XML Content-Length: 667 <?XML version = “1.0” encoding = “UTF-8”?> <visualization_scenario_customization_output> <response_identifier>ID_response_34</response_identifier> <visualization_data> portfolio return metrics data (e.g., constituent securities' and/or portfolio's returns, worst returns, return volatility, frequency vs. returns data) </visualization_data> </visualization_scenario_customization_output>

FIG. 21 shows a logic flow illustrating embodiments of a scenario based portfolio returns visualizing (SPRV) component for the MLPO. In FIG. 21, a portfolio returns visualization request may be obtained at 2101. For example, the portfolio returns visualization request may be obtained as a result of a user requesting generation of a portfolio returns visualization.

Market scenarios to utilize for generating the portfolio returns visualization may be determined at 2105. In one embodiment, the market scenarios to utilize may be determined based on the simulation model (e.g., for a specified pricing date) and/or time period length selected by the user. In another embodiment, the market scenarios to utilize may be determined based on filters applied to simulated market scenarios. In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the market scenarios to utilize (e.g., based on the values of the simulation_model and/or pricing_date fields). For example, the selected simulation model and/or pricing date may be used to determine a simulation identifier (e.g., ID_sim_1) of the corresponding simulation (e.g., a set of simulated market scenarios).

Portfolio securities of a portfolio may be determined at 2109 and portfolio securities weights for the portfolio securities may be determined at 2113. In one embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be retrieved from a database (e.g., based on a portfolio identifier). In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the portfolio identifier (e.g., based on the value of the portfolio_identifier field). In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be specified by the user. In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the specified portfolio securities and/or the corresponding portfolio securities weights. In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be determined based on an optimization. In one implementation, the portfolio securities and/or the corresponding portfolio securities weights may be determined as discussed with regard to the PC component.

Expected returns of the portfolio securities for the market scenarios to utilize may be retrieved from a database at 2117. For example, the expected returns may be cached to facilitate expected return metrics calculations. In one implementation, the expected returns may be retrieved via an expected returns retrieve request.

A determination may be made at 2121 whether there remain portfolio securities to process. In one implementation, each of the constituent portfolio securities may be processed. If there remain portfolio securities to process, the next security (e.g., with identifier MSFT) may be selected for processing at 2125.

A determination may be made at 2129 whether there remain market scenarios to analyze. In one implementation, each of the market scenarios to utilize may be analyzed. If there remain market scenarios to analyze, the next market scenario (e.g., with identifier ID_scenario_1) may be selected for analysis at 2133.

An expected return for the selected security for the selected market scenario may be determined at 2137. In one implementation, the expected return may be retrieved from cache. In another implementation, the expected return may be retrieved from a database. For example, the expected return for the selected security for the selected market scenario may be determined via a MySQL database command similar to the following:

SELECT linkedScenarioSecurityExpectedReturn FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1 AND linkedScenarioID = ID_scenario_1;

Expected security return metrics for the selected security for the market scenarios to utilize may be calculated at 2141. For example, the expected security return metrics for a security may include the security's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In one implementation, the expected security return metrics for each security may be determined by iterating through the market scenarios to utilize and calculating the expected security return metrics based on the expected returns (e.g., cached) for the market scenarios to utilize. For example, the expected return for the selected security for the market scenarios to utilize may be determined via a MySQL database command similar to the following:

SELECT AVG(linkedScenarioSecurityExpectedReturn) FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1;

Expected portfolio return metrics for the portfolio for the market scenarios to utilize may be calculated at 2145. For example, the expected portfolio return metrics for a portfolio may include the portfolio's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the expected portfolio return metrics for the portfolio may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of the expected security returns and/or of the calculated expected security return metrics for the constituent securities of the portfolio. For example, the following API may be utilized to determine the expected portfolio return metrics for the portfolio for the market scenarios to utilize:

POST API/RUNANALYSIS

-   -   This API facilitates generating portfolio return metrics         visualization for a specified portfolio (e.g., list of         securities). The portfolio return metrics calculation results         are included in the Summary object returned by the API.     -   The API returns HTTP/1.1 status code 201 if the request is         successful. It returns 500 Internal Server Error if there is an         exception.

A visualization of the expected portfolio return metrics for the portfolio and/or of the expected security return metrics for the constituent securities of the portfolio for the market scenarios to utilize may be generated at 2149. In one implementation, user interface widgets showing the expected portfolio return metrics and/or the expected security return metrics may be generated via a portfolio returns visualization response. See FIGS. 22-25 for examples of visualizations that may be generated.

A determination may be made at 2153 whether a predefined scenario selection input was obtained from the user. In one embodiment, the predefined scenario selection input may be a user interface input from the user with a user-specified predefined scenario selection. For example, the user may select a predefined scenario to determine how expected portfolio return metrics for the portfolio and/or for the constituent securities of the portfolio would change with market factor customizations specified in the predefined scenario.

If a predefined scenario selection input was obtained, the set of customized market factors associated with the selected predefined scenario may be determined at 2157. In one implementation, the market factor customizations specified in the predefined scenario may be obtained via a predefined scenario retrieve response, and the predefined scenario retrieve response may be parsed (e.g., using PHP commands) to determine the set of customized market factors (e.g., based on the values of the market_factor_identifier fields).

The market scenarios to utilize may be filtered based on the set of customized market factors at 2161. In one embodiment, the market scenarios to utilize may be filtered to the subset of market scenarios that satisfy the subrange of allowable values for each customized market factor. See FIG. 14B for additional details regarding filtering the market scenarios to utilize based on customized market factors. In another embodiment, the market scenarios to utilize also may be filtered based on specified business cycle settings (e.g., as discussed with regard to FIG. 27).

Expected security return metrics for the portfolio securities for the filtered market scenarios may be calculated at 2165. In one implementation, the expected security return metrics for each constituent security of the portfolio may be determined by iterating through the filtered market scenarios and calculating the expected security return metrics based on the expected returns (e.g., cached) for the filtered market scenarios. For example, the expected return for a constituent security (e.g., MSFT) of the portfolio for the filtered market scenarios may be determined via a MySQL database command similar to the following:

SELECT AVG(linkedScenarioSecurityExpectedReturn) FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1 AND linkedScenarioID IN (ID_scenario_1, ID_scenario_2, ...);

Expected portfolio return metrics for the portfolio for the filtered market scenarios may be calculated at 2169. In various implementations, the expected portfolio return metrics for the portfolio may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of the expected security returns and/or of the calculated expected security return metrics for the constituent securities of the portfolio (e.g., via the API).

A visualization of the expected portfolio return metrics for the portfolio and/or of the expected security return metrics for the constituent securities of the portfolio for the filtered market scenarios may be generated at 2173. In one implementation, user interface widgets showing the expected portfolio return metrics and/or the expected security return metrics may be generated (e.g., via a portfolio returns visualization response, via a visualization scenario customization output). See FIGS. 22-25 for examples of visualizations that may be generated.

A determination may be made at 2177 whether a market factor customization input was obtained from the user (e.g., via a visualization scenario customization input). In one embodiment, the market factor customization input may be a user interface input from the user with a user-specified range of allowable values for an updated market factor. If a market factor customization input was obtained, the specified range of allowable values for the updated market factor may be determined at 2181. In one implementation, the visualization scenario customization input may be parsed (e.g., using PHP commands) to determine the specified range of allowable values for the updated market factor (e.g., based on the values of the market_factor_identifier, minimum_range_value, and/or maximum_range_value fields). The set of customized market factors may be updated at 2185. In one implementation, a list (e.g., an array of market factor identifiers, a map of market factor identifier values to customized status Boolean values) of customized market factors may be updated. Market scenarios to utilize may be filtered based on the updated set of customized market factors and an updated visualization of the expected portfolio return metrics for the portfolio and/or of the expected security return metrics for the constituent securities of the portfolio may be generated as discussed with regard to 2161-2173.

FIG. 25 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 25, an exemplary user interface (e.g., for a mobile device, for a website) for generating a portfolio returns visualization for a portfolio is illustrated. Screen 2501 shows that when the user modifies the range of allowable values for a market factor, an updated visualization showing how the expected portfolio return metrics for the portfolio and/or the expected security return metrics for the constituent securities of the portfolio have been affected may be generated. For example, the user may utilize an allowable range widget 2510A to modify the range of allowable values (e.g., a customization) for the VIX market factor. The updated visualization shows how the range of allowable values (e.g., shown in an allowable range widget 2510B) for the SP500 market factor has been affected (e.g., based on the updated set of filtered market scenarios). The updated visualization shows that the user may utilize a drawdown widget 2525 to view the expected loss (e.g., −20.25%) at the worst CVaR percentile outcomes for the portfolio under the customized predefined scenario, the expected loss (e.g., −9.42%) at the worst CVaR percentile outcomes for the portfolio under the original predefined scenario, and the difference in the expected loss at the worst CVaR percentile outcomes (e.g., −10.83) between the two scenarios. The updated visualization shows that the user may utilize a return volatility widget 2530 to view the return volatility (e.g., 4.51%) for the portfolio under the customized predefined scenario, the return volatility (e.g., 4.15%) for the portfolio under the original predefined scenario, and the difference in the expected return volatility (e.g., 0.36%) between the two scenarios. The updated visualization shows that the user may utilize a returns distribution widget 2535 to view the returns distribution for the portfolio under the customized predefined scenario, the returns distribution for the portfolio under the original predefined scenario, and the difference in the expected returns distribution between the two scenarios. The user may utilize a portfolio securities weights widget 2540 to view and/or modify portfolio securities weights of individual portfolio securities of the portfolio under the customized predefined scenario. The user may utilize a portfolio securities returns widget 2545 to view expected returns of individual portfolio securities of the portfolio under the customized predefined scenario.

The MLPO server 2606 may send a portfolio returns visualization response 2637 to the user client 2604 to provide a visualization of portfolio return metrics for the specified portfolio under the specified business cycle settings. In one implementation, the portfolio returns visualization response may include data such as a response identifier, visualization data, and/or the like. In one embodiment, the MLPO server may provide the following example portfolio returns visualization response, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

If the user customizes business cycle settings, the user client 2604 may send a visualization business cycle customization input 2641 to the MLPO server 2606 specifying updated business cycle settings. In one implementation, the visualization business cycle customization input may include data such as a request identifier, business cycle settings, and/or the like. In one embodiment, the user client may provide the following example visualization business cycle customization input, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

The MLPO server 2606 may send a visualization business cycle customization output 2645 to the user client 2604 to provide an updated visualization of portfolio return metrics for the specified portfolio (e.g., under the modified business cycle settings). In one implementation, the visualization business cycle customization output may include data such as a response identifier, visualization data, and/or the like. In one embodiment, the MLPO server may provide the following example visualization business cycle customization output, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

FIG. 27 shows a logic flow illustrating embodiments of a business cycle based portfolio returns visualizing (BPRV) component for the MLPO. In FIG. 27, a portfolio returns visualization request may be obtained at 2701. For example, the portfolio returns visualization request may be obtained as a result of a user requesting generation of a portfolio returns visualization.

Market scenarios to utilize for generating the portfolio returns visualization may be determined at 2705. In one embodiment, the market scenarios to utilize may be determined based on the simulation model (e.g., for a specified pricing date) and/or time period length selected by the user. In another embodiment, the market scenarios to utilize may be determined based on filters applied to simulated market scenarios. In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the market scenarios to utilize (e.g., based on the values of the simulation_model and/or pricing_date fields). For example, the selected simulation model and/or pricing date may be used to determine a simulation identifier (e.g., ID_sim_1) of the corresponding simulation (e.g., a set of simulated market scenarios).

Portfolio securities of a portfolio may be determined at 2709 and portfolio securities weights for the portfolio securities may be determined at 2713. In one embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be retrieved from a database (e.g., based on a portfolio identifier). In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the portfolio identifier (e.g., based on the value of the portfolio_identifier field). In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be specified by the user. In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the specified portfolio securities and/or the corresponding portfolio securities weights. In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be determined based on an optimization. In one implementation, the portfolio securities and/or the corresponding portfolio securities weights may be determined as discussed with regard to the PC component.

Expected returns of the portfolio securities for the market scenarios to utilize may be retrieved from a database at 2717. For example, the expected returns may be cached to facilitate expected return metrics calculations. In one implementation, the expected returns may be retrieved via an expected returns retrieve request.

A determination may be made at 2721 whether there remain portfolio securities to process. In one implementation, each of the constituent portfolio securities may be processed. If there remain portfolio securities to process, the next security (e.g., with identifier MSFT) may be selected for processing at 2725.

A determination may be made at 2729 whether there remain market scenarios to analyze. In one implementation, each of the market scenarios to utilize may be analyzed. If there remain market scenarios to analyze, the next market scenario (e.g., with identifier ID_scenario_1) may be selected for analysis at 2733.

An expected return for the selected security for the selected market scenario may be determined at 2737. In one implementation, the expected return may be retrieved from cache. In another implementation, the expected return may be retrieved from a database. For example, the expected return for the selected security for the selected market scenario may be determined via a MySQL database command similar to the following:

SELECT linkedScenarioSecurityExpectedReturn FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1 AND linkedScenarioID = ID_scenario_1;

Expected security return metrics for the selected security for the market scenarios to utilize may be calculated at 2741. For example, the expected security return metrics for a security may include the security's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In one implementation, the expected security return metrics for each security may be determined by iterating through the market scenarios to utilize and calculating the expected security return metrics based on the expected returns (e.g., cached) for the market scenarios to utilize. For example, the expected return for the selected security for the market scenarios to utilize may be determined via a MySQL database command similar to the following:

SELECT AVG(linkedScenarioSecurityExpectedReturn) FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1;

Expected portfolio return metrics for the portfolio for the market scenarios to utilize may be calculated at 2745. For example, the expected portfolio return metrics for a portfolio may include the portfolio's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the expected portfolio return metrics for the portfolio may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of the expected security returns and/or of the calculated expected security return metrics for the constituent securities of the portfolio. For example, the following API may be utilized to determine the expected portfolio return metrics for the portfolio for the market scenarios to utilize:

POST API/RUNANALYSIS

-   -   This API facilitates generating portfolio return metrics         visualization for a specified portfolio (e.g., list of         securities). The portfolio return metrics calculation results         are included in the Summary object returned by the API.     -   The API returns HTTP/1.1 status code 201 if the request is         successful. It returns 500 Internal Server Error if there is an         exception.

A visualization of the expected portfolio return metrics for the portfolio and/or of the expected security return metrics for the constituent securities of the portfolio for the market scenarios to utilize may be generated at 2749. In one implementation, user interface widgets showing the expected portfolio return metrics and/or the expected security return metrics may be generated via a portfolio returns visualization response. See FIGS. 28-30 for examples of visualizations that may be generated.

A determination may be made at 2753 whether a business cycle selection input was obtained from the user. In one embodiment, the business cycle selection input may be a user interface input from the user with a user-specified business cycle selection. For example, the user may select a business cycle (e.g., using a user interface widget to select a specific business cycle, using a user interface widget to request that the MLPO determine the appropriate business cycle (e.g., the business cycle under which the portfolio has the best or the worst expected return metrics)) to determine how expected portfolio return metrics for the portfolio and/or for the constituent securities of the portfolio would change given occurrence of the business cycle (e.g., during the investment time period). In another example, the user may select multiple business cycles, and an associated weight (e.g., probability of occurrence) for each business cycle, to determine how expected portfolio return metrics for the portfolio and/or for the constituent securities of the portfolio would change given business cycle expectations (e.g., during the investment time period).

If a business cycle selection input was obtained, the specified set of business cycles and/or associated business cycle weights may be determined at 2755. In one implementation, the set of business cycles and/or the associated business cycle weights may be specified in a visualization business cycle customization input, and the visualization business cycle customization input may be parsed (e.g., using PHP commands) to determine the specified set of business cycles and/or the associated business cycle weights (e.g., based on the values of the business_cycle_identifier and/or business_cycle_weight fields).

A determination may be made at 2757 whether there remain business cycles to process. In one implementation, each of the specified business cycles may be processed. If there remain business cycles to process, the next business cycle may be selected for processing at 2759.

The market scenarios to utilize may be filtered based on the selected business cycle at 2761. In one embodiment, the market scenarios to utilize may be filtered to the subset of market scenarios that are associated with the selected business cycle. In one implementation, each market scenario to utilize may be associated with a business cycle identifier (e.g., indicating a business cycle during which a simulated market scenario would have occurred), and market scenarios to utilize whose business cycle identifiers do not match the business cycle identifier of the selected business cycle may be filtered out. In another embodiment, the market scenarios to utilize also may be filtered based on specified customized market factors (e.g., as discussed with regard to FIG. 21).

Expected security return metrics for the portfolio securities for the filtered market scenarios may be calculated at 2765. In one implementation, the expected security return metrics for each constituent security of the portfolio for the selected business cycle may be determined by iterating through the filtered market scenarios and calculating the expected security return metrics based on the expected returns (e.g., cached) for the filtered market scenarios. For example, the expected return for a constituent security (e.g., MSFT) of the portfolio for the filtered market scenarios may be determined via a MySQL database command similar to the following:

SELECT AVG(linkedScenarioSecurityExpectedReturn) FROM ExpectedReturns WHERE securityID = “MSFT” AND linkedSimulationID = ID_sim_1 AND linkedScenarioID IN (ID_scenario_1, ID_scenario_2, ...);

Expected portfolio return metrics for the portfolio for the filtered market scenarios may be calculated at 2769. In various implementations, the expected portfolio return metrics for the portfolio for the selected business cycle may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of the expected security returns and/or of the calculated expected security return metrics for the constituent securities of the portfolio (e.g., via the API) for the selected business cycle.

Once the specified business cycles have been processed, weighted expected security return metrics for the portfolio securities for the specified business cycles may be calculated at 2773. For example, the weighted expected security return metrics for a security may include the security's weighted expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the weighted expected security return metrics for a constituent security for the specified business cycles may be calculated using a weighted average (e.g., weighted based on the associated business cycle weights) of the expected security returns for the constituent security for each of the specified business cycles and/or of the calculated expected security return metrics for the constituent security for each of the specified business cycles.

Weighted expected portfolio return metrics for the portfolio for the specified business cycles may be calculated at 2777. For example, the weighted expected portfolio return metrics for a portfolio may include the portfolio's weighted expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the weighted expected portfolio return metrics for the portfolio for the specified business cycles may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of the calculated weighted expected security return metrics for the constituent securities of the portfolio and/or using a weighted average (e.g., weighted based on the associated business cycle weights) of the calculated expected portfolio return metrics for the portfolio for each of the specified business cycles (e.g., via the API).

A visualization of the weighted expected portfolio return metrics for the portfolio and/or of the weighted expected security return metrics for the constituent securities of the portfolio for the specified business cycles may be generated at 2781. In one implementation, user interface widgets showing the weighted expected portfolio return metrics and/or the weighted expected security return metrics may be generated (e.g., via a portfolio returns visualization response, via a visualization business cycle customization output). See FIGS. 28-30 for examples of visualizations that may be generated.

A determination may be made at 2785 whether a business cycle weight selection input was obtained from the user (e.g., via a visualization business cycle customization input). In one embodiment, the business cycle weight selection input may be a user interface input from the user with user-specified business cycle weights for the specified business cycles. If a business cycle weight selection input was obtained, the specified business cycle weights for the specified business cycles may be updated at 2789. In one implementation, the visualization business cycle customization input may be parsed (e.g., using PHP commands) to determine the updated business cycle weights (e.g., based on the values of the business_cycle_weight fields). A determination may be made at 2793 whether the expected portfolio return metrics for the portfolio for each of the specified business cycles and/or the expected security return metrics for the constituent securities of the portfolio for each of the specified business cycles are cached (e.g., from a previous calculation that used different business cycle weights for the specified business cycles). If cached, an updated visualization of the weighted expected portfolio return metrics for the portfolio and/or of the weighted expected security return metrics for the constituent securities of the portfolio for the specified business cycles may be generated as discussed with regard to 2773-2781. If not cached, an updated visualization of the weighted expected portfolio return metrics for the portfolio and/or of the weighted expected security return metrics for the constituent securities of the portfolio for the specified business cycles may be generated as discussed with regard to 2757-2781.

FIG. 28 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 28, an exemplary user interface (e.g., for a mobile device, for a website) for generating a portfolio returns visualization for a portfolio is illustrated. Screen 2801 shows that a user may utilize a business cycle tab 2803 to specify business cycle settings. The user may utilize business cycle selection widgets 2805A-B to specify business cycles to utilize. For example, business cycle selection widget 2805A shows some exemplary business cycles that may be selected by the user. The user may utilize business cycle weight selection widgets 2810A-B to specify business cycle weights to utilize. For example, the user may specify that a portfolio returns visualization should be generated based on an expectation that the Late business cycle (e.g., selected using business cycle selection widget 2805A) is going to occur with 100% probability (e.g., selected using business cycle weight selection widget 2810A). The user may utilize a positioning widget 2815 to request that the MLPO determine the appropriate business cycle. For example, the user may specify that a portfolio returns visualization should be generated for the business cycle under which the portfolio has the best expected returns (e.g., Late business cycle).

Screen 2801 shows that the user may utilize a returns distribution widget 2835 to view the returns distribution of the portfolio under the original business cycle settings. The user may utilize a portfolio securities weights widget 2840 to view and/or modify portfolio securities weights of individual portfolio securities of the portfolio under the original business cycle settings. The user may utilize a portfolio securities returns widget 2845 to view expected returns of individual portfolio securities of the portfolio under the original business cycle settings.

FIG. 29 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 29, an exemplary user interface (e.g., for a mobile device, for a website) for generating a portfolio returns visualization for a portfolio is illustrated. Screen 2901 shows that when the user modifies the business cycle settings an updated visualization showing how the expected portfolio return metrics for the portfolio and/or the expected security return metrics for the constituent securities of the portfolio have been affected may be generated. For example, the user may specify that the updated portfolio returns visualization should be generated based on an expectation (e.g., a customization) that the Late business cycle (e.g., selected using business cycle selection widget 2905A) is going to occur with 85% probability (e.g., selected using business cycle weight selection widget 2910A) and the Recession business cycle (e.g., selected using business cycle selection widget 2905B) is going to occur with 15% probability (e.g., selected using business cycle weight selection widget 2910B). The updated visualization shows that the user may utilize a drawdown widget 2925 to view the expected loss (e.g., −1.30%) at the worst CVaR percentile outcomes for the portfolio under the customized business cycle settings, the expected loss (e.g., −0.99%) at the worst CVaR percentile outcomes for the portfolio under the original business cycle settings, and the difference in the expected loss at the worst CVaR percentile outcomes (e.g., −0.31) between the two business cycle settings. The updated visualization shows that the user may utilize a return volatility widget 2930 to view the return volatility (e.g., 0.55%) for the portfolio under the customized business cycle settings, the return volatility (e.g., 0.40%) for the portfolio under the original business cycle settings, and the difference in the expected return volatility (e.g., 0.15%) between the two business cycle settings. The updated visualization shows that the user may utilize a returns distribution widget 2935 to view the returns distribution for the portfolio under the customized business cycle settings, the returns distribution for the portfolio under the original business cycle settings, and the difference in the expected returns distribution between the two business cycle settings. The user may utilize a portfolio securities weights widget 2940 to view and/or modify portfolio securities weights of individual portfolio securities of the portfolio under the customized business cycle settings. The user may utilize a portfolio securities returns widget 2945 to view expected returns of individual portfolio securities of the portfolio under the customized business cycle settings. The user may utilize an optimize widget 2950 to determine an optimized portfolio under the customized business cycle settings (e.g., determined based on the updated weighted expected security returns for the constituent securities of the portfolio). The user may utilize an execute widget 2955 to initiate the execution of tradeable buy and/or sell transactions utilized to create the optimized portfolio under the customized business cycle settings.

FIG. 30 shows a screenshot illustrating user interface(s) of the MLPO. In FIG. 30, an exemplary user interface (e.g., for a mobile device, for a website) for generating a portfolio returns visualization for a portfolio is illustrated. Screen 3001 shows that the user may utilize a positioning widget 3015 to request that the MLPO determine the appropriate business cycle. For example, the user may specify that a portfolio returns visualization should be generated for the business cycle (e.g., a customization) under which the portfolio has the worst expected returns (e.g., Early business cycle (e.g., as shown by business cycle selection widgets 3005A-B) with 100% probability (e.g., as shown by business cycle weight selection widgets 3010A-B)). The updated visualization shows that the user may utilize a drawdown widget 3025 to view the expected loss (e.g., −1.19%) at the worst CVaR percentile outcomes for the portfolio under the customized business cycle settings, the expected loss (e.g., −0.99%) at the worst CVaR percentile outcomes for the portfolio under the original business cycle settings, and the difference in the expected loss at the worst CVaR percentile outcomes (e.g., −0.20) between the two business cycle settings. The updated visualization shows that the user may utilize a return volatility widget 3030 to view the return volatility (e.g., 0.45%) for the portfolio under the customized business cycle settings, the return volatility (e.g., 0.40%) for the portfolio under the original business cycle settings, and the difference in the expected return volatility (e.g., 0.05%) between the two business cycle settings. The updated visualization shows that the user may utilize a returns distribution widget 3035 to view the returns distribution for the portfolio under the customized business cycle settings, the returns distribution for the portfolio under the original business cycle settings, and the difference in the expected returns distribution between the two business cycle settings. The user may utilize a portfolio securities weights widget 3040 to view and/or modify portfolio securities weights of individual portfolio securities of the portfolio under the customized business cycle settings. The user may utilize a portfolio securities returns widget 3045 to view expected returns of individual portfolio securities of the portfolio under the customized business cycle settings.

FIG. 34 shows a datagraph illustrating data flow(s) for the MLPO. In FIG. 34, a client 3402 (e.g., of a user) may send a portfolio returns visualization request 3421 to an application server 3406 to facilitate generating a portfolio returns visualization (e.g., based on customized market factors as discussed with regard to FIG. 20, based on specified business cycle settings as discussed with regard to FIG. 26, for constructing an optimized bond ladder portfolio as discussed with regard to FIG. 37). For example, the client may be a desktop, a laptop, a tablet, a smartphone, a smartwatch, and/or the like that is executing a client application. In one implementation, the portfolio returns visualization request may include data such as a request identifier, a user identifier, a predefined scenario identifier, business cycle settings, a simulation model, a pricing date, a portfolio identifier, investment securities settings, and/or the like. In one embodiment, the client may provide the following example portfolio returns visualization request, substantially in the form of a (Secure) Hypertext Transfer Protocol (“HTTP(S)”) POST message including eXtensible Markup Language (“XML”) formatted data, as provided below:

A portfolio returns visualizing (PRV) component 3425 may utilize data provided in the portfolio returns visualization request to generate a portfolio return metrics visualization based on asset return metrics provided by a database calculation engine. In some embodiments, the PRV component may be an optimized version of the SPRV component (e.g., discussed with regard to FIG. 21), BPRV component (e.g., discussed with regard to FIG. 27), and/or the like components (e.g., a component used to implement a bond ladder construction process discussed with regard to FIG. 48) that utilizes the database calculation engine for improved performance. See FIG. 35 for additional details regarding the PRV component.

The application server 3406 may send an asset return metrics calculation request 3429 to a database server 3410 to obtain asset return metrics for securities in the portfolio for simulated scenarios corresponding to the specified simulation (e.g., with a simulation identifier determined based on the specified pricing date and/or simulation model). In one implementation, the asset return metrics calculation request may include data such as a request identifier, asset return metrics to retrieve specification, and/or the like. In one embodiment, the application server may provide the following example asset return metrics calculation request, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

The application server 3406 may send a portfolio returns visualization response 3441 to the client 3402 to provide a visualization of portfolio return metrics for the specified portfolio. In one implementation, the portfolio returns visualization response may include data such as a response identifier, visualization data, and/or the like. In one embodiment, the application server may provide the following example portfolio returns visualization response, substantially in the form of a HTTP(S) POST message including XML-formatted data, as provided below:

FIG. 35 shows a logic flow illustrating embodiments of a portfolio returns visualizing (PRV) component for the MLPO. In FIG. 35, a portfolio returns visualization request may be obtained at 3501. For example, the portfolio returns visualization request may be obtained as a result of a user requesting generation of a portfolio returns visualization.

Market scenarios to utilize for generating the portfolio returns visualization may be determined at 3505. In one embodiment, the market scenarios to utilize may be determined based on the simulation model (e.g., for a specified pricing date) and/or time period length selected by the user. In another embodiment, the market scenarios to utilize may be determined based on filters applied to simulated market scenarios. In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the market scenarios to utilize (e.g., based on the values of the simulation_model and/or pricing_date fields). For example, the selected simulation model and/or pricing date may be used to determine a simulation identifier (e.g., ID_sim_1) of the corresponding simulation (e.g., a set of simulated market scenarios).

Portfolio securities of a portfolio may be determined at 3509 and portfolio securities weights for the portfolio securities may be determined at 3513. In one embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be retrieved from a database (e.g., based on a portfolio identifier). In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the portfolio identifier (e.g., based on the value of the portfolio_identifier field). In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be specified by the user (e.g., via a set of securities universe widgets as discussed with regard to FIG. 10, via a set of security selection widgets as discussed with regard to FIG. 41). In one implementation, the portfolio returns visualization request may be parsed (e.g., using PHP commands) to determine the specified portfolio securities and/or the corresponding portfolio securities weights. In another embodiment, the portfolio securities and/or the corresponding portfolio securities weights may be determined based on an optimization. In one implementation, the portfolio securities and/or the corresponding portfolio securities weights may be determined as discussed with regard to the PC component. In another implementation, the portfolio securities and/or the corresponding portfolio securities weights may be determined as discussed with regard to FIG. 48.

Asset return metrics data for the portfolio securities may be obtained via the ARMC component at 3517. In one embodiment, an application (e.g., executed by an application server) may be configured to generate a portfolio returns visualization comprising a set of visualization return metrics, and the asset return metrics data utilized to calculate the set of visualization return metrics may be obtained using the database calculation engine (e.g., via an asset return metrics calculation request). In one implementation, asset simulation wide table data (e.g., utilized for calculating expected portfolio return metrics for the portfolio) and/or asset measure table data (e.g., utilized for calculating expected security return metrics for the constituent securities of the portfolio) may be obtained. See 706 in FIG. 7C for an example of asset simulation wide table data. See 710 in FIG. 7C for an example of asset measure table data.

A determination may be made at 3521 whether there remain visualization return metrics to determine. In one implementation, each of the visualization return metrics in the set of visualization return metrics may be determined. If there remain visualization return metrics to determine, the next visualization return metric may be selected for processing at 3525.

A determination may be made at 3529 regarding the type of the selected visualization return metric. In one embodiment, a visualization return metric may be an expected portfolio return metric calculated for a portfolio. In another embodiment, a visualization return metric may be an expected security return metric calculated for a security.

If the selected visualization return metric type is portfolio, the selected expected portfolio return metric for the portfolio may be determined using the asset simulation wide table data at 3533. For example, expected portfolio return metrics for a portfolio may include the portfolio's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the selected expected portfolio return metric for the portfolio may be calculated using a weighted average (e.g., weighted based on the portfolio securities weights) of expected security returns and/or of determined expected security return metrics for the constituent securities of the portfolio using the asset simulation wide table data. For example, the following API may be utilized to determine expected portfolio return metrics, in the set of visualization return metrics, for the portfolio for the market scenarios to utilize:

If the selected visualization return metric type is security, the selected expected security return metric for the portfolio securities of the portfolio may be determined using the asset measure table data at 3537. For example, expected security return metrics for a security may include the security's expected return, worst returns, return volatility, frequency vs. returns data, and/or the like. In various implementations, the selected expected security return metric for each security may be determined (e.g., retrieved, calculated) using the asset measure table data. For example, the following API may be utilized to determine expected security return metrics, in the set of visualization return metrics, for the portfolio securities of the portfolio for the market scenarios to utilize:

A visualization of the expected portfolio return metrics for the portfolio and/or of the expected security return metrics for the constituent securities of the portfolio for the market scenarios to utilize may be generated at 3541. In one implementation, user interface widgets showing the expected portfolio return metrics and/or the expected security return metrics may be generated via a portfolio returns visualization response. See FIGS. 22-25, 28-30, and 41-47 for examples of visualizations that may be generated.

FIG. 36 shows a logic flow illustrating embodiments of an asset return metrics calculating (ARMC) component for the MLPO. In FIG. 36, an asset return metrics calculation request may be obtained at 3601. For example, the asset return metrics calculation request may be obtained as a result of an application requesting calculation of asset return metrics data.

Assets to analyze may be determined at 3605. In one embodiment, asset return metrics data may be calculated for the determined assets. In one implementation, the asset return metrics calculation request may be parsed (e.g., using PHP commands) to determine the assets (e.g., a set of portfolio securities) to analyze (e.g., based on the value of the securities field). In another implementation, the assets (e.g., a universe of securities (e.g., bonds)) to analyze may be determined (e.g., to precalculate and/or cache asset return metrics data) based on a configuration setting.

A simulation identifier to utilize may be determined at 3609. In one embodiment, the simulation identifier may identify a set of simulated market scenarios to utilize to calculate asset return metrics data. See FIGS. 2A-B and FIG. 4 for additional details regarding the MLSSP component, which may be used to generate simulated market scenarios. In one implementation, the asset return metrics calculation request may be parsed (e.g., using PHP commands) to determine the simulation identifier (e.g., based on the value of the simulation_identifier field).

A pricing date to utilize may be determined at 3613. In one embodiment, the pricing date may represent the date for which analytics (e.g., Key Rate Durations (KRD), Option Adjusted Spread, Muni KRDs, etc.) for the assets are available and/or when asset simulations are calculated. In one implementation, the asset return metrics calculation request may be parsed (e.g., using PHP commands) to determine the pricing date (e.g., based on the value of the pricing_date field). In another implementation, the latest available pricing date may be utilized.

Assets may be filtered based on available factor exposures at 3617. In one embodiment, such filtering is a data reduction technique utilized to reduce the number of records used during calculations thus lowering processing time. In one implementation, the factor exposure table (e.g., factor_expo table in FIG. 40) may comprise data calculated for assets that have analytics available, while the assets table (e.g., asset table in FIG. 40) may comprise data for the available assets (e.g., assets in the universe of securities, assets in the set of portfolio securities). This filtering ensures that those assets for which factor exposures are available are processed. In various implementations, assets may be processed using sessions (e.g., as discussed with regard to 3633) with each session targeting specific range of assets to be processed. For example, if the assets are processed in 4 sessions, the first session may target the first 250K assets, the second session may target assets from 250K to 500K, and so on. Each session may be configured to have access to its own set of global temporary tables that is used to store information related to the assets the respective session is processing (e.g., data may not be shared between sessions). Reducing the assets to those assets that are processed by a session and storing in a global temporary table for the session ensures that big table joins are eliminated during the asset return calculation process. In some implementations, the asset return calculation process may be rerunnable, and may be configured to ignores the assets that are already processed in the previous run. For example, the assets may be filtered based on available factor exposures via an Oracle RDS on Cloud database command similar to the following:

-   -   In the query below, the factor exposure is reduced to the assets         being targeted in the session and further reduced to ignore         assets that are already processed if the asset return         calculation process is rerun.

INSERT INTO <db-schema>.global_asset_list SELECT DISTINCT fe.asset_id FROM (SELECT DISTINCT asset_id FROM <db-schema>.factor_expo WHERE pricing_dt = lc_truncatedPricingDate ORDER BY asset_id offset p_offset ROWS FETCH NEXT p_rangeVal ROWS ONLY) fe LEFT OUTER JOIN (SELECT DISTINCT asset_id FROM <db-schema>.asset_sim_wide am WHERE am.pricing_dt = lc_truncatedPricingDate) asw ON (fe.asset_id = asw.asset_id) WHERE asw.asset_id IS NULL;

Factor simulations may be filtered based on the filtered assets at 3621. In one embodiment, such filtering is a data reduction technique utilized to reduce the number of records used during calculations thus lowering processing time. In one implementation, the factor simulations table (e.g., factor_sim table in FIG. 40) may comprise simulated returns for market factors (e.g., 40+ factors which is around 300K records). This filtering determines a set of market factors to which the filtered assets have exposure (e.g., this reduces the number of factor simulation records that are loaded by 50%, to around 150K records, and/or reduces the JOIN for further processing). In some implementations, a factor simulation may contain factor simulation data for multiple simulations with multiple simulation dates. Filtering the table to include targeted simulation ids reduces the number of records that are utilized for calculations. Each asset may have exposure to certain factors and using the factors that the targeted assets have exposure to can further reduce the size of the factor simulation table that is processed. For example, for 250K assets, the unique factors that these assets have access to may be 10 instead of 40+ factors for which factor simulations are available. Reducing the factor simulation to include factor simulations for fewer factors reduce the number of records. Also, storing the data in temporary table instead of using the main table reduces the need to filter data during calculations. For example, the factor simulations may be filtered based on the filtered assets via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.mglobal_factor_sim_tmp SELECT * FROM <db-schema>.factor_sim fs WHERE fs.sim_id IN (p_simIdQuarterly, p_simIdBiAnnually, p_simIdYearly) AND fs.factor_id IN ( SELECT DISTINCT factor_id FROM <db-schema>.factor_expo fe INNER JOIN <db-schema>.global_asset_list gal ON fe.asset_id = gal.asset_id WHERE fe.pricing_dt = lc_truncatedPricingDate )

In some implementations, the factor exposure table and the factor simulations table may be augmented to integrate the impact of convexity in asset simulation. The convexity metric (e.g., option adjusted convexity) may be obtained from Sentinel's security_master table. The factor exposure table may be augmented by inserting convexity as (e.g., two) new market factors (e.g., id 80 for non-muni instruments, id 81 for muni instruments). For example, the exposure table may be augmented via an Oracle RDS on Cloud database command similar to the following:

SELECT cusip as asset_id, 80 as factor_id, 1/2 * security_master.option_adjusted_convexity / 10000 as exposure FROM security_master WHERE product_name != ‘Municipal’ UNION ALL SELECT cusip as asset_id, 81 as factor_id, 1/2 * security_master.option_adjusted_convexity / 10000 as exposure FROM security_master WHERE product_name = ‘Municipal’

The factor simulations table may be augmented by inserting the square of the change in yield (e.g., using the average return of different key rates as the proxy for the change in yield) as (e.g., two) new market factors (e.g., id 80 for Treasury curves, id 81 for muni curves) for each simulation and each market scenario. For example, the factor simulations table may be augmented via an Oracle RDS on Cloud database command similar to the following:

/* Treasury curves 3M, 6M, 1Y, 2Y, 3Y, 5Y, 7Y, 10Y, 20Y, 30Y Muni curves 2Y, 5Y, 10Y, 20Y */ with oac_factor as ( select fs.sim_id, fs.market_id, power(avg(fs.return), 2) as return, case when f.type = ‘Treasury Curves’ then 80 when f.type = ‘Muni Curves’ then 81 end as factor_id from factor_sim fs, factor f where fs.factor_id = f.id and fs.factor_id in (select f.id from factor f where f.type = ‘Treasury Curves’ or f.type = ‘Muni Curves’) group by fs.sim_id, f.type, fs.market_id order by fs.market_id ) select distinct fs.sim_id, fs.market_id, fs.bucket_id, oo.factor_id, oo.return from oac_factor oo, factor_sim fs where oo.sim_id=fs.sim_id and oo.market_id=fs.market_id order by sim_id, market_id

Factor exposures may be filtered based on the filtered assets and/or the pricing date at 3625. In one embodiment, such filtering is a data reduction technique utilized to reduce the number of records used during calculations thus lowering processing time. In one implementation, the factor exposure table may store factor exposures for assets for multiple pricing dates (e.g., for the last three runs/dates). This filtering determines a set of factor exposure records for the pricing date (e.g., for the current pricing date and filters out records for older pricing dates) that are associated with the filtered assets (e.g., assets for which factor exposures are available). For example, the factor exposures may be filtered based on the filtered assets and/or the pricing date via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.mglobal_factor_expo_tmp SELECT fe.* FROM <db-schema>.factor_expo fe INNER JOIN <db-schema>.global_asset_list gal ON fe.asset_id = gal.asset_id WHERE fe.pricing_dt = lc_truncatedPricingDate;

Call and/or put schedules may be filtered based on the filtered assets at 3629. In one embodiment, such filtering is a data reduction technique utilized to reduce the number of records used during calculations thus lowering processing time. In one implementation, the call schedule table (e.g., call_schedule table in FIG. 40) and/or the put schedule table (e.g., put_schedule table in FIG. 40) may comprise call and/or put prices for the available assets (e.g., assets in the universe of securities, assets in the set of portfolio securities). This filtering determines a set of call and/or put schedule records that are associated with the filtered assets (e.g., assets for which factor exposures are available). For example, the call and/or put schedules may be filtered based on the filtered assets via an Oracle RDS on Cloud database command similar to the following:

-   -   The query below is separated out into two parts. The first part         focuses on getting the call and put price based on different         horizons and call date. The second part focuses on calculating         the call and put returns which will result in defining the lower         cap of the simulated returns.

The number of sessions to utilize for calculating asset return metrics data may be determined at 3633. In one embodiment, asset return metrics data may be calculated using parallel queries with a specified degree of parallelism. Accordingly, each parallel query may be processed using a number of query server processes corresponding to the specified degree of parallelism. In various implementations, the degree of parallelism for a parallel query may be specified at the statement level, at the session level, at the table level, at the index level, and/or the like. For example, a parallel query may specify that 8 query server processes should be used for processing the parallel query. In one implementation, the number of sessions to utilize may be determined based on available server resources to maintain a consistent degree of parallelism by creating a balance between sessions and parallel query server processes (e.g., threads). For example, for a server having 32 processors (e.g., CPUs, physical cores, virtual cores), 4 sessions may be utilized (e.g., determined by dividing the number of available processors by the specified degree of parallelism). Each session may be utilized for calculating asset return metrics data as discussed with regard to 3637-3693.

An assets range for a session may be determined at 3637. In one embodiment, an assets range for a session may refer to the set of assets to be processed by the session. In one implementation, the assets range for the session may be determined by dividing the filtered assets based on the number of sessions. For example, if there are in total 800K filtered assets for which asset return metrics data should be calculated, the filtered assets may be divided into 4 sets of assets each targeting 200K unique assets, and the session may be assigned 1 of the 4 sets of assets as the session's session assets.

A determination may be made at 3641 whether there remain session assets to analyze. In one implementation, each of the session's session assets may be analyzed. If there remain session assets to analyze, a batch size to utilize may be determined at 3645. In one implementation, the batch size may be specified in a configuration setting. For example, the batch size may be configured to be 1000 assets. In another implementation, the batch size may depend on the number of assets that remain to be analyzed. For example, if 300 assets remain to be analyzed, then the batch size may be 300 assets instead of 1000 assets.

A temporary table of session assets of the determined batch size may be created at 3649. In one implementation, a session assets batch of the determined batch size may be selected from the session assets that remain to be analyzed. For example, the temporary table comprising the session assets batch may be created via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.global_asset_id_distinct_tmp SELECT asset_id FROM <db-schema>.global_asset_list ORDER BY asset_id ASC offset lv_startIndex ROWS FETCH NEXT lv_loopIncrement ROWS ONLY;

A temporary table of factor simulations for the session assets batch may be created at 3653. In one implementation, the temporary table of factor simulations may be created by transposing factor simulations to store factor simulations for simulation ids representing different time horizons (e.g., this may reduce the number of records in the join as data related to different simulations are available in columns, making the expected returns calculation as discussed with regard to 3661 three times faster). For example, the temporary table of factor simulations for the session assets batch may be created via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO pfmofrdbo.global_factor_sim_tmp SELECT * FROM (SELECT fs2.market_id, fs2.factor_id, fs2.sim_id AS sim_id, fs2.return AS RETURN FROM (SELECT fs.* FROM <db-schema>.mglobal_factor_sim_tmp fs WHERE fs.factor_id IN (SELECT DISTINCT factor_id FROM <db-schema>.global_factor_expo_tmp) ) fs2 WHERE fs2.sim_id IN (p_simIdQuarterly, p_simIdBiAnnually, p_simIdYearly) ) PIVOT (SUM(RETURN) FOR (sim_id) IN (20 AS return_quarterly, 21 AS return_biannual, 22 return_yearly));

A temporary table of factor exposures for the session assets batch may be created at 3657. In one implementation, the temporary table of factor exposures may be created by selecting filtered factor exposures for the session assets batch. For example, the temporary table of factor exposures for the session assets batch may be created via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.global_factor_expo_tmp SELECT fe.* FROM <db-schema>.mglobal_factor_expo_tmp fe JOIN <db-schema>.global_asset_id_distinct_tmp age ON fe.asset_id = age.asset_id WHERE fe.pricing_dt = lc_truncatedPricingDate;

Expected returns for the session assets batch may be calculated via parallel execution (e.g., via a parallel query) at 3661. In one implementation, the expected returns for the session assets batch may be calculated as the sum product of the factor exposures for the session assets batch and the simulated returns of filtered factor simulations for the session assets batch. For example, the expected returns for the session assets batch may be calculated via parallel execution via an Oracle RDS on Cloud database command similar to the following:

SELECT /*+ full(f) full(e) parallel(f 8) parallel(e 8) */ e.asset_id asset_id, f.market_id, SUM(e.exposure * f.return_quarterly) return_quarterly, SUM(e.exposure * f.return_biannual) return_biannual, SUM(e.exposure * f.return_yearly) return_yearly FROM <db-schema>.global_factor_sim_tmp f JOIN <db-schema>.global_factor_expo_tmp e ON (f.factor_id = e.factor_id) GROUP BY e.asset_id, f.market_id

The expected returns for the session assets batch may be adjusted based on call and/or put schedules via parallel execution (e.g., via a parallel query) at 3665. In one implementation, if an asset has an embedded call option redeemable within the investment horizon, the return from exercising the call option may be set as the upper bound of the simulated asset return, and/or if an asset has an embedded put option redeemable within the investment horizon, the return from exercising the put option may be set as the lower bound of the simulated asset return. For example, the call/put option schedules (e.g., including redemption dates and prices) may be obtained from Sentinel's call_schedule/put_schedule tables via an Oracle RDS on Cloud database command similar to the following:

SELECT as1.pricing_dt, as1.sim_id, as1.asset_id, as1.market_id, greatest(least(as1.simulated_return, (cs.next_call_price / sm.current_instrument_price − 1) * 10000), (ps.next_put_price / sm.current_instrument_price − 1) * 10000) FROM asset_sim as1, security_master sm, call_schedule cs, put_schedule ps WHERE as1.asset_id = sm.cusip AND as1.asset_id = cs.cusip AND as1.asset_id = ps.cusip AND cs.earliest_next_call_date <= as1.investment_horizon AND ps.earliest_next_put_date <= as1.investment_horizon

For example, the expected returns for the session assets batch may be adjusted based on call and/or put schedules via parallel execution via an Oracle RDS on Cloud database command similar to the following:

SELECT /*+ full(asim) full(scp) parallel(asim 8) parallel(scp 8) */ asim.asset_id, asim.market_id, GREATEST(GREATEST(scp.put_price_factor_3m, LEAST(asim.return_quarterly, scp.call_price_factor_3m ) ) + scp.quarterly_horizon_factor, −10000) return_quarterly, GREATEST(GREATEST(scp.put_price_factor_6m, LEAST(asim.return_biannual, scp.call_price_factor_6m ) ) + scp.biannual_horizon_factor,−10000) return_biannual, GREATEST(GREATEST(scp.put_price_factor_1y, LEAST(asim.return_yearly, scp.call_price_factor_1y ) ) + scp.yearly_horizon_factor,−10000) return_yearly FROM (SELECT /*+ full(f) full(e) parallel(f 8) parallel(e 8) */ e.asset_id asset_id, f,market_id, ... <complete query from 0391> ) asim JOIN <db-schema>.global_call_put_prices scp ON scp.asset_id = asim.asset_id ;

The expected returns for the session assets batch may be transposed into array format at 3669. In one embodiment, the wide array format may facilitate improved performance when calculating portfolio level return metrics. For example, the expected returns for the session assets batch may be transposed into array format via an Oracle RDS on Cloud database command similar to the following:

-   -   Custom data type asset_sim_return_data_type is used to store an         array of decimal values. Each decimal value is split into two         parts (e.g., X.Y where X represents the CVaR value and Y         represents the market id). Storing both CVaR metric and the         associated market id allows storing data in one variable instead         of two thus saving storage. This also allows parallel execution         of collecting returns in the array format and maintaining the         market ids for which each of the returns are associated with.

SELECT /*+ full(asim) parallel(asim 8) */ asim.asset_id, lc_truncatedPricingDate AS pricing_dt, CAST ( COLLECT( TO_BINARY_DOUBLE(TRUNC(asim.return_quarterly)+ SIGN(asim.return_quarterly)* ((asim.market_id*10) +1 )/ 1000000 )) AS ASSET_SIM_RETURN_DATA_TYPE) return_quarterly, CAST ( COLLECT( TO_BINARY_DOUBLE(TRUNC(asim.return_biannual) + SIGN(asim.return_biannual)* ((asim.market_id*10) +1 )/ 1000000 )) AS ASSET_SIM_RETURN_DATA_TYPE) return_biannual, CAST ( COLLECT( TO_BINARY_DOUBLE(TRUNC(asim.return_yearly) + SIGN(asim.return_yearly)* ((asim.market_id*10) +1 )/ 1000000 ) )AS ASSET_SIM_RETURN_DATA_TYPE) return_yearly FROM <db-schema>.global_asset_sim_tmp asim GROUP BY asim.asset_id ) UNPIVOT (RETURN FOR sim_id IN (return_quarterly AS 20, return_biannual AS 21, return_yearly AS 22)

The transposed expected returns for the session assets batch may be written to the asset simulation wide table via parallel execution (e.g., via a parallel query) at 3673. In one implementation, the asset simulation wide table (e.g., asset_sim_wide table in FIG. 40) may be written to in parallel by query server processes from the utilized sessions (e.g., by up to 32 query server processes when utilizing 4 sessions with degree of parallelism of 8). For example, the transposed expected returns for the session assets batch may be written to the asset simulation wide table via parallel execution via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.asset_sim_wide /*+ parallel(8) NO_GATHER_OPTIMIZER_STATISTICS */ SELECT * FROM (SELECT  /*+ full(asim) parallel(asim 8) */  asim.asset_id,  lc_truncatedPricingDate AS pricing_dt,  CAST ( COLLECT(  TO_BINARY_DOUBLE(TRUNC(asim.return_quarterly)+  ... <complete query from 3669>

A determination may be made at 3677 whether there remain asset return metrics to calculate for the session assets batch. In one implementation, each of the asset return metrics (e.g., requested asset return metrics specified in the asset return metrics calculation request, default asset return metrics specified in a configuration setting) may be calculated. If there remain asset return metrics to calculate, the next asset return metric may be selected at 3681. For example, asset return metrics may include a security's expected return, worst returns (CVaR), return volatility, and/or the like.

The selected asset return metric for the session assets batch may be calculated via parallel execution (e.g., via a parallel query) at 3685. For example, the average of 5% worst returns may be calculated for the CVaR asset return metric. In one implementation, the selected asset return metric for the session assets batch may be calculated in accordance with an applicable formula for the selected asset return metric. For example, the selected asset return metric (e.g., CVaR) for the session assets batch may be calculated via parallel execution via an Oracle RDS on Cloud database command similar to the following:

-   -   The query below shows how CVaR measure is calculated in parallel         based on available asset returns for a single horizon. Similar         queries may be run for bi-annual and annual horizons.         lc_truncatedPricingDate holds the pricing date for which the         batch is run, lv_marketCount holds the number of markets used         for simulations and lv_marketPercentageForCvar holds the         percentage value used for calculating the CVaR (e.g., average of         the worst 5% returns).

SELECT  /*+ parallel(8) */  lc_truncatedPricingDate pricing_dt,  asim.asset_id,  p_simIdQuarterly,  ‘CVAR’ measure_name,  NULL AS factor_id,  NULL AS market_id,  AVG(asim.return_quarterly) measure_value FROM  (SELECT *  FROM (SELECT asim.asset_id,  asim.return_quarterly,  ROW_NUMBER( ) OVER( PARTITION BY asim.asset_id ORDER BY asim.return_quarterly ) rk FROM <db-schema>.global_asset_sim_tmp asim ) asim  WHERE rk <= lv_marketPercentageForCvar * lv_marketCount  ) asim GROUP BY asim.asset_id;

The selected asset return metric for the session assets batch may be written to the asset measure table via parallel execution (e.g., via a parallel query) at 3689. In one implementation, the asset measure table (e.g., asset_measure table in FIG. 40) may be written to in parallel by query server processes from the utilized sessions (e.g., by up to 32 query server processes when utilizing 4 sessions with degree of parallelism of 8). For example, the selected asset return metric (e.g., CVaR) for the session assets batch may be written to the asset measure table via parallel execution via an Oracle RDS on Cloud database command similar to the following:

INSERT INTO <db-schema>.asset_measure /*+ parallel(8) NO_GATHER_OPTIMIZER_STATISTICS */ SELECT /*+ parallel(8) */ lc_truncatedPricingDate pricing_dt, asim.asset_id, p_simIdQuarterly, ‘CVAR’ measure_name, ... <complete query from 3685>

The temporary tables created for the session assets batch may be cleared at 3693. In one embodiment, the temporary tables created for the session assets batch may be cleared to reduce temporary storage utilization. For example, the temporary tables created for the session assets batch may be cleared via an Oracle RDS on Cloud database command similar to the following:

EXECUTE IMMEDIATE ‘TRUNCATE TABLE <db-schema>.global_asset_id_distinct_tmp DROP STORAGE’; EXECUTE IMMEDIATE ‘TRUNCATE TABLE <db-schema>.global_factor_expo_tmp DROP STORAGE’; EXECUTE IMMEDIATE ‘TRUNCATE TABLE <db-schema>.global_factor_sim_tmp DROP STORAGE’; EXECUTE IMMEDIATE ‘TRUNCATE TABLE <db-schema>.global_asset_sim_tmp DROP STORAGE’;

Asset return metrics data from the asset simulation wide table and/or the asset measure table may be provided to the requesting application at 3697. In one implementation, the asset return metrics data may be provided via an asset return metrics calculation response. In some implementations, global temporary tables may be cleaned up using Data Definition Language (DDL) statements for faster execution.

INSERT INTO Factor Expo /*+ parallel(8) NO_GATHER_OPTIMIZER_STATISTICS */ SELECT /*+ full(a) parallel(a 8) */ case b.factor_id when 50 then -- exposure for muni 2Y when 55 then -- exposure for muni 5Y when 280 then - dimension reduction using median OAS ... end FROM INST_REF_ANALYTICS_TEMP a INNER JOIN SECURITYTYPE_FACTOR_TEMP b on a.product_type = b.product_type

Enabling unprecedented market stress scenarios to be generated following the observed unprecedentedness pattern from history

The unprecedentedness of a historical scenario is described as the number of Δ factors that take unprecedented values compared to historical scenarios prior to that date. The plot in FIG. 65 visualizes the relationship between Δ VIX and historical unprecedentedness. In this example, a degree 2 polynomial is used to represent the relationship because as Δ VIX becomes more extreme in both ends, greater number of Δ factors taking unprecedented values are expected to show up. The fitted degree 2 polynomial curve is the historical unprecedentedness curve.

As shown in FIG. 65, a large VIX change comes with unseen changes in market risk factors.

The unprecedentedness of a transfer-layer VAE simulated scenario is described to be the number of Δ factors that take unprecedented values compared to historical scenarios. The plot in FIG. 66 shows that simulation output from transfer-layer VAE fails to reflect the relation shown above, with almost all scenarios having 0 unprecedentedness. The reason is that VAE restores the historical scenarios very well so it is not surprising we are unable to see more extreme Δ factors values.

As shown in FIG. 66, a Deep Learning Model captures each factor's history closely but neglects other factors' related new extremes.

Following what has been done to calculate VAE unprecedentedness, we can apply it to panic simulated market scenarios. The goal is to make the relationship between Δ VIX and stress sim unprecedentedness to look alike to the relationship in historical unprecedentedness section. The approach is to find the mean squared error between the unprecedentedness curves. See FIGS. 68, 69, and 70.

For example, as shown in FIG. 67, by selecting historical scenarios with either Δ VIX<−1000 or Δ VIX>3062 to compute mean and covariance and then fit a multivariate normal distribution and sample the same number of scenarios as in history, the relationship fitted from simulated scenarios will be alike to the historical.

A component of the market scenario simulation is a deep learning model, variational autoencoder. To take advantage of the cloud compute power, in one implementation, a machine learning service, SageMaker, may be used in AWS. SageMaker is a fully managed service that provides an efficient way for developers and data scientists to collaborate together to build, train, tune, and deploy models in a machine learning pipeline. With SageMaker, the model training and tuning process can be conveniently run in a parallel and distributed way on multiple instances and multiple GPUs. In addition, the one-click deployment feature of SageMaker significantly reduces the effort to deploy a machine learning model. For example, with the parallel computing architecture using SageMaker, the training time of multiple models may be reduced to 2 minutes in total, while training multiple models sequentially with single instance and single CPU takes 45 minutes, as shown in FIG. 72.

Simulating Mutual Fund and ETF Asset Returns

The Mutual Fund and ETF returns simulation model employs a set of machine learning techniques to estimate 3-month, 6-month and 1-year returns under simulated market scenarios while allowing for domain experts to incorporate their subjective views. FIG. 49 illustrates the overall model architecture. In one implementation, parallel computing may be used to implement training and deployment of a unique model for each mutual fund or ETF. As FIG. 50 demonstrates, the process of loading data from database tables, performing feature engineering, training model and writing results to database may be distributed to multiple processors and conducted simultaneously. FIG. 51 summarizes the database tables containing model input and output. For each fund or ETF, the returns during specified investment horizons are aggregated geometrically from daily returns. Domain experts have the option of specifying a pool of potential market factors to be considered by the feature selection procedure for a particular fund or ETF. If no factors are specified by experts, available market factors will be considered. To select the set of market factors that contribute the most to overall model performance and mitigate the problem of multicollinearity, a proprietary feature selection procedure is designed to utilize XGBoost to rank the feature importance levels of available market factors, and feed the factors with positive importance scores to a customized forward selection process, which selects a set of factors that maximizes the model's adjusted R-squared as well as restrains model coefficients from changing signs (see FIG. 52). Subsequently, a Ridge Regression model is trained to learn the relationship between a fund's or ETF's historical returns and those of the selected set of market factors using 75% of historical data points, is validated using the remaining 25% of historical data points based on a number of metrics, including out-of-sample adjusted R-squared, effect size of residual distribution, residual correlation, etc., and is utilized to estimates its returns under stimulated market environments. FIG. 53 illustrates the market risk factor exposures based on the regression models as presented in the UI. To account for a fund or ETF's active risk not captured by common market factors, regression residuals from the model validation stage are randomly sampled and added to the simulated fund or ETF returns. Lastly, the estimated returns may be calibrated to reflect capital market assumptions provided by economists. FIGS. 54 and 55 present the distributions of simulated returns under user-defined market scenarios and different business cycles, respectively.

Simulating Equity Asset Returns

Individual Equity returns for different time horizons are aggregated geometrically with daily return, which is adjusted for corporate actions such as stock split and dividend. Daily return may be used instead of price because price can have huge jump caused by corporate actions. Feature selection may be utilized before model training. It uses an XGBoost model to select a subset of features that contribute to positive gain in feature importance ranking and then feeds these selected features to a forward selection process, which further extracts features that improve adjusted R square (see FIG. 56). Both Ridge regression (e.g., used in forward selection with adjusted R square) and XGBoost regression at the last step deal with multi-collinearity problem. Based on the CAPM model, an asset's risk has 2 components: one is market risk driven, one is idiosyncratic risk driven. Building the 2 parts separately allows models to better capture the behavior of different risk components. Intuition for conditional beta modeling is that based on historical observation, equities' correlation to market index can vary under different market scenarios, and correlation from different equities can also vary. Conditional beta model captures individual equity's sensitivity to market index across the simulated market scenarios and formulates the market risk driven part. Intuition for idiosyncratic risk modeling is that based on historical observation, beta risk from broad market index partially explains an equity's total return, and the other key part is company specific risk, which in this case is revealed from company financials data and default probability. Combining conditional beta model and idiosyncratic risk model, a more comprehensive total risk simulation is generated matching the CAPM's explanation. During training phase, realized beta is calculated using linear regression of individual equity's return series against market index's return series for a selected time horizon. Modeling for 3M, 6M, and 12M are separated since market scenario simulation and financials factors capture their own dependencies under different time horizons. To account for residual analysis, a few validations were done. 1. Effective size (Cohen's D measure) was close to zero. 2. Residual correlation to target variable was close to zero. 3. Residual was unbiased. Residuals are stored during training phase, randomly sampled during scoring phase, and added to simulated conditional beta to better capture market driven risk. Conditional beta modeling uses broad common market risk factors as features, including macro factors, equity indices, and smart beta factors. To simulate individual equity's conditional beta against market index, simulated market scenarios are used. Conditional beta modeling may be implemented with parallel computing on EMR notebook, which uses AWS cloud environment and utilizes clusters to do the training Generated models for each individual equity may be directly written into a Postgres database in binary format through a driver (see FIG. 62). Company specific returns are modeled with feature importance weighted historical sampling. During model training phase, feature importance is stored. During scoring phase, if a simulated market scenario can be mapped to individual equity's existing historical scenario, then the excess return over market index for this specific historical scenario is used. Otherwise, a Euclidian distance is calculated weighted by feature importance from selected risk features, and excess return over market index for the closest historical scenario is used. Total return is calculated combining beta return and idiosyncratic return. Simulated returns for each equity are stored in an array format in Postgres table.

EMR Notebook is used in simulating asset returns concurrently on Cloud Technology platform for mutual funds, ETFs, equities and fixed income instruments. In Financial Services Industry, as data sets grow rapidly and complexly, the data transformation, data storage, and the users' real-time operations end up with a huge burden. Big data frameworks may be employed to support the data process and storage, and they allow the data to be generated and stored in a parallel and distributed way. Spark and Hadoop are examples of compute engines for big data that may be utilized. The principle of the compute engine in Spark is to analyze computation tasks and optimize the workflow of the data processing before actually executing the code. Spark may utilize Directed Acyclic Graph (DAG) optimizations and in memory processing.

Spark has been integrated into many cloud services, such as Elastic Map Reduce (EMR) provided by Amazon Web Service (AWS). In one implementation, EMR may be utilized to make full usage of compute power offered by the cloud provider and save compute costs, since the EMR runtime for Spark can be over 3 times faster than standard Spark. Using cloud provided service may help to improve the performance of workloads without making extra changes to the applications.

In one implementation, in order to improve the development efficiency, EMR Notebooks may be used along with EMR clusters to submit Spark jobs for parallel computing. EMR Notebook is a managed notebook environment which is based on the open-source Jupyter notebook. It supports submitting Spark code to EMR clusters through Apache Livy.

In one implementation, the Optimizer is developed based on parallel computation capability and advanced numerical optimization methodologies, such as Tail Risk Optimizer and Mean-Variance Optimizer, in order to provide optimal portfolio within 3M, 6M and 1Y horizon and user specified conditions. It evaluates the portfolio expected return, portfolio volatility and portfolio drawdown, equipped with flexible scenarios choices and business Cycle overview.

For Tail Risk Optimizer, mixed integer programming, binary integer programming and linear programming with rounding techniques are available. CVaR-Mean frontier can be shaped with the optimizer parallel computation ability and then illustrate the relationship between CVaR and expected return. Different CVaR-Mean frontier can be visualized according to diversification preferences (see FIG. 71) and market scenarios. The mixed integer programming can offer more accurate results according to asset price and asset tradable amount while the linear programming with rounding techniques guarantees faster performance on large scale computation (See FIG. 72).

For the Mean-Variance Optimizer, the portfolio risk is measured by covariance matrix that can be estimated through two different methods in the tool. “Shifted Diagonal” method adjusts original sample covariance matrix diagonal to decrease asset correlation influence in optimization, and “Ledoit-Wolf” method gives a robust estimation by minimizing the quadratic loss function.

In one implementation, the optimizer attempts to maximize the portfolio return with a risk penalty whose value is decided by risk tolerance parameter. The 0 risk tolerance will lead the optimizer to minimize the risk at all costs and the infinity risk tolerance will maximize the return at all costs. In the tool, the risk tolerance has been mapped from 0 to 10 to be user friendly.

Similarly, the efficient frontier of Mean Variance Optimizer can be presented according to investors' preferences as well as various market scenarios. Optimal portfolio weights may be generated varying risk aversion in the convex optimization with user specified weights constrains and market scenario. This set of optimal solutions the optimizer generated would form a frontier line and the optimal solution of current risk tolerance level would be a big red dot on the previous frontier and should move along on the efficient frontier when risk tolerance parameter changes (see FIG. 73). Thus, the change of risk tolerance level may not change the efficient frontier shape, but the changes of diversification and market scenarios may lead to a reshaped efficient frontier (see FIG. 74 and FIG. 75).

Multi-Risk Factor Risk Engine and Portfolio Aggregation Using Oracle RDS on Cloud

Using Oracle RDS on Cloud, a SQL-based solution effectively utilizes different parallel execution techniques for calculating simulation data. Conditional risk simulation can now be calculated for over a million assets using a faster, simple, cost effective and scalable solution using Oracle RDS on Cloud in substantially less amount of time. Computations happens on the database server, eliminating having to transfer a huge set of data to external systems for processing and therefore maximizes processing of data using cloud computing.

The first step of the process is to calculate Factor Exposures for available assets as shown in FIG. 76. Based on available reference data and analytics, the spread ratio is calculated for the available assets in parallel. The second step is to calculate simulated returns for the available assets as shows in FIG. 77. The process of generating simulated asset returns may involve, getting unique list of assets for which exposure data is available and loading the factor exposures for assets with exposure to the factors and loading factor simulations for those factors (see FIG. 78). The process then splits the workload into smaller chunks with each chunk processing a subset of the assets. The simulated returns for the assets are then calculated, adjusted using available call and put schedule, and written to the database using several parallel computing techniques as listed below (see FIG. 79).

Convexity Adjustment—To integrate the impact of convexity in asset simulation, it may be included as an additional term in the dot product following these steps. The convexity metric (option adjusted convexity) is obtained from Sentinel's security_master table.

Step 1: Insert convexity as two new “factors” (id 80 for non-muni instruments, 81 for muni instruments) in the factor_expo table (see FIG. 80). Step 2: For each simulation id and each market scenario (market_id), insert the square of the change in yield as two new “factors” (id 80 for Treasury curves, 81 for muni curves) in the factor_sim table. In one implementation, the average return of different key rates may be used as the proxy for the change in yield (see FIG. 81).

Treasury curves 3M, 6M, 1Y, 2Y, 3Y, 5Y, 7Y, 10Y, 20Y, 30Y

Muni curves 2Y, 5Y, 10Y, 20Y

Optionality Adjustment—If an instrument has an embedded call (or put) option redeemable within the investment horizon, the return from exercising the call (or put) option may be set as the upper (or lower) bound of the simulated asset return. The call (or put) option schedules, including redemption dates and prices, are obtained from Sentinel's call_schedule (or put_schedule) tables (see FIG. 82).

In one implementation, several data reduction, scaling and parallel computing techniques may be utilized. For example, innovative ways to use global temporary tables and sessions, data reduction techniques to drastically limit amount of data utilized for processing thus lowering processing time, and several other data parallelization techniques for generating simulation data may be utilized.

1. Use of Multiple Batches to achieve higher degree of parallelism (DOP) 2. Use of Global Temporary Tables (GTT) to be able to run batch in multiple sessions and reduce temporary storage requirements 3. Use of Data Reduction techniques to reduce full table scans for joins between Factor Exposure and Factor Simulation table 4. Use of Parallel Query to parallelize generation of Asset Simulation and Contribution to Value at Risk data 5. Use of Parallel DML to parallelize inserting data related to Asset Simulation and Contribution to Value at Risk 6. Use of DDL for faster execution of delete statements to speed up cleanup of global temporary tables (see FIG. 79)

Tail-Risk Adjusted Bond Ladder Construction

Tail-risk adjusted bond ladder construction is the capability to construct a bond ladder incorporating real-time market offerings, user-defined search criteria, and pre-trade scenario risk analysis (see FIG. 93). In some implementations, the tail-risk adjusted bond ladder construction process is a rule based approach that avoids the use of a solver, which allows a large number of bond market offerings to be evaluated in real-time, guarantees portfolio construction solutions based on market offerings, and provides consistent and scalable calculation performance. The bond-ladder construction logic (see FIG. 88) uses the real-time bond offering from electronic bond trading venues. Real-time data fusion technologies provide the list of bonds and prices from multiple sources of liquidity. The logic also ensures the market values across the rungs of the bond ladder are approximately equal (see FIG. 94). The proposed bond ladder is built with approximately equal market values across the different rungs of the bond ladder (see FIG. 95). Market value is calculated using allocated par amount and prices from real-time bond offerings.

In one implementation, the bond ladder construction may use two separate modes—Yield Maximization and Risk Score Adjusted to construct the ladder (see FIG. 93). Under Yield Maximization mode (see FIG. 96), the offerings are first organized into classifications according to product type, credit rating, and final maturity. The classifications can then be further screened by user-defined search criteria resulting with the (e.g., one hundred) highest yielding securities presented per rung as ladder portfolio options. Ladder options may be allocated within the portfolio up to a user-defined diversification constraint (“Maximum Security Exposure”). By doing this, the user can specify that the market value of any individual position should not exceed a percentage threshold of the total market value of the portfolio. Under Risk Score Adjusted mode (see FIG. 97), the offerings are first organized into classifications according to product type, credit rating, and final maturity. The classifications can then be further screened by user-defined search criteria. The resulting set of securities are then run through the model which takes the offering yield to worst and performs a calculation on each to arrive at a down-side risk score. Down-side risk is quantified using a statistical measure calculated as a zscore, sourced from either the security's default probability or its 5% worst mark-to-market estimated total returns, also known as the 5% conditional value-at-risk (CVaR).

For bonds which are covered by Kamakura Corporation's default risk model, default probabilities may be used as the down-side risk score. Default probabilities are published daily by Kamakura for public, private and sovereign issuers across multiple time horizons. Default probabilities may be updated for these issuers using the following tenors: 1 Month, 3 Months, 6 Months, 1 Yr, 2 Yr, 4 Yr, 5 Yr, 7 Yr, 10 Yr. These time horizons are matched with the time to maturities of the bonds in the bond offerings. For bonds not covered by Kamakura's default risk model, down-side risk may be quantified as CVaR calculated based on a proprietary risk model. A normalized risk score is calculated for available bond offerings for each rung. The bonds' yield to worst may be adjusted by the risk score. Bond offerings with lower down-side risk rank higher; bond offerings with higher risk rank lower.

Steps for Tail-risk Adjusted Bond Ladder Construction

1. Get Available Bonds from Offers API based on inputs provided in the Strategy Settings and Security Selected screen of Bond Beacon (see FIG. 89) 2. Check if Risk Score Adjustment option is selected as the Yield Maximization Method. If Yes, continue with Step #3 below otherwise, continue to Step #5. 3. Calculate and store MEAN and STDDEV based on data available for Conditional Value at Risk (CVAR) and Default Probability. These values will be used later to calculate z-score and adjustment to yield. 4. Check each security available for allocation and adjust their yield

a. If the security has default probability, calculate z-score using the following formula

z-score=(DEFAULTinstrument−DEFAULTmean)/DEFAULTstddev

Adjusted Yield=yield*(1−z-score/10)

b. If no default probability data is available for the security, calculate z-score based on the following formula

z-score=(CVARinstrument−CVARmean)/CVARstddev

Adjusted Yield=yield*(1+z-score/10)

5. Run the bond allocation logic based on Adjusted Yield. If No Risk Score Adjustment option is selected, Adjusted Yield equals to the Yield of the security (see FIG. 90 for output generated from the bond ladder construction logic).

a. Sort available bonds based on Adjusted Yield, Rating and Available Quantity to Trade

b. Calculate Quantity to Allocated in PAR for security based on Minimum Denomination, Minimum Increment and Diversification Limit (in MV)

c. Check for Minimum Balance Remaining based on Calculated Quantity to Allocate. If Minimum Balance Remaining Condition is not satisfied, skip the bond and continue.

d. Check if the rung has enough cash for allocation based on allocated MV for security.

-   -   i. If rung has enough cash, allocate and adjust rung MV     -   ii. If run does not have enough cash, repeat step 5.a using         available rung's cash as the limit Continue with steps 5.a, 5.b         and 5.c.         6. Check if Residual Cash is remaining after Bond Allocation

a. Find Rung with highest yield.

-   -   i. Using bonds currently allocated within a rung, find the yield         based on weighted average calculations.     -   ii. Find the rung with the highest average yield.

b. For all bonds currently available in the rung, run the bond allocation logic as listed in Step #5

Scenario-Based Risk Reporting for Multiple User-Specified Scenarios

Scenario-based Risk Reporting may be implemented as part of an application programming interface (API) which uses parallel processing for calculating risk-based analytics for user specified scenarios.

The first step of the process is to load simulated returns for available securities in parallel (see FIG. 83). If simulated returns are not available for the specified securities (see FIG. 91), a real-time asset simulation process is executed. This real-time process generates the simulated returns for the securities in real-time by applying data reduction methods for loading factor exposures and simulated factor returns from the database (see FIG. 87) for the factors the securities has exposures to. The data reduction method reduces the data loaded for calculating the simulated returns by reducing the data to the factors the securities have exposures to. This eliminates redundant data being loaded and supports the factor executing of dot product calculations utilized for generating the simulated returns (see FIG. 86).

The second step is to filter out markets based on the input scenarios (occurrence of a situation or changes to key factor such as, change in interest rates) or business cycles (a business cycle is the natural rise and fall of economic growth that occurs over time) specified by the user. For example, if user has created a scenario with a criteria in which the U.S. 2 Year Treasury Rate is between 0.3 and 1.8%, the process creates a map of markets for which the simulated returns for securities falls within this range. The process is executed in parallel for available user-defined scenarios and specified securities. If a particular user-defined scenario has multiple such criteria, additional filter logic is applied on top of previously filtered markets. Once the target list of markets is available for each user-defined scenario, the process filters the simulated returns for securities and reduces the data to the targeted markets available.

The final step is to calculate the weighted average simulated returns for the filtered markets based on the weight specified as part of the input for each security. The process then calculates risk-level analytics such as, CVAR based on filtered simulated returns. The results are then presented to the user (see FIG. 92). FIG. 98 shows the Market Sensitivity Chart that shows how a particular portfolio performs under different user-defined scenarios and business cycles.

This single dimensional array is a unique data format to support     aggregate portfolio simulated returns in parallel. This data format     eliminates the complexity to maintain mapping of the returns to     market scenarios. At the API layer, in processing this single     dimensional array in parallel, there is no need for     compression/decompression logic.)

MLPO Controller

FIG. 99 shows a block diagram illustrating embodiments of a MLPO controller. In this embodiment, the MLPO controller 9901 may serve to aggregate, process, store, search, serve, identify, instruct, generate, match, and/or facilitate interactions with a computer through machine learning and database systems technologies, and/or other related data.

Users, which may be people and/or other systems, may engage information technology systems (e.g., computers) to facilitate information processing. In turn, computers employ processors to process information; such processors 9903 may be referred to as central processing units (CPU). One form of processor is referred to as a microprocessor. CPUs use communicative circuits to pass binary encoded signals acting as instructions to allow various operations. These instructions may be operational and/or data instructions containing and/or referencing other instructions and data in various processor accessible and operable areas of memory 9929 (e.g., registers, cache memory, random access memory, etc.). Such communicative instructions may be stored and/or transmitted in batches (e.g., batches of instructions) as programs and/or data components to facilitate desired operations. These stored instruction codes, e.g., programs, may engage the CPU circuit components and other motherboard and/or system components to perform desired operations. One type of program is a computer operating system, which, may be executed by CPU on a computer; the operating system enables and facilitates users to access and operate computer information technology and resources. Some resources that may be employed in information technology systems include: input and output mechanisms through which data may pass into and out of a computer; memory storage into which data may be saved; and processors by which information may be processed. These information technology systems may be used to collect data for later retrieval, analysis, and manipulation, which may be facilitated through a database program. These information technology systems provide interfaces that allow users to access and operate various system components.

In one embodiment, the MLPO controller 9901 may be connected to and/or communicate with entities such as, but not limited to: one or more users from peripheral devices 9912 (e.g., user input devices 9911); an optional cryptographic processor device 9928; and/or a communications network 9913.

Networks comprise the interconnection and interoperation of clients, servers, and intermediary nodes in a graph topology. It should be noted that the term “server” as used throughout this application refers generally to a computer, other device, program, or combination thereof that processes and responds to the requests of remote users across a communications network. Servers serve their information to requesting “clients.” The term “client” as used herein refers generally to a computer, program, other device, user and/or combination thereof that is capable of processing and making requests and obtaining and processing any responses from servers across a communications network. A computer, other device, program, or combination thereof that facilitates, processes information and requests, and/or furthers the passage of information from a source user to a destination user is referred to as a “node.” Networks are generally thought to facilitate the transfer of information from source points to destinations. A node specifically tasked with furthering the passage of information from a source to a destination is called a “router.” There are many forms of networks such as Local Area Networks (LANs), Pico networks, Wide Area Networks (WANs), Wireless Networks (WLANs), etc. For example, the Internet is, generally, an interconnection of a multitude of networks whereby remote clients and servers may access and interoperate with one another.

Optionally, a cryptographic processor 9926 may be connected to the system bus. In another embodiment, the cryptographic processor, transceivers (e.g., ICs) 9974, and/or sensor array (e.g., accelerometer, altimeter, ambient light, barometer, global positioning system (GPS) (thereby allowing MLPO controller to determine its location), gyroscope, magnetometer, pedometer, proximity, ultra-violet sensor, etc.) 9973 may be connected as either internal and/or external peripheral devices 9912 via the interface bus I/O 9908 (not pictured) and/or directly via the interface bus 9907. In turn, the transceivers may be connected to antenna(s) 9975, thereby effectuating wireless transmission and reception of various communication and/or sensor protocols; for example the antenna(s) may connect to various transceiver chipsets (depending on deployment needs), including: Broadcom® BCM4329FKUBG transceiver chip (e.g., providing 802.11n, Bluetooth 2.1+EDR, FM, etc.); a Broadcom® BCM4752 GPS receiver with accelerometer, altimeter, GPS, gyroscope, magnetometer; a Broadcom® BCM4335 transceiver chip (e.g., providing 2G, 3G, and 4G long-term evolution (LTE) cellular communications; 802.11ac, Bluetooth 4.0 low energy (LE) (e.g., beacon features)); a Broadcom® BCM43341 transceiver chip (e.g., providing 2G, 3G and 4G LTE cellular communications; 802.11 g/, Bluetooth 4.0, near field communication (NFC), FM radio); an Infineon Technologies® X-Gold 618-PMB9800 transceiver chip (e.g., providing 2G/3G HSDPA/HSUPA communications); a MediaTek® MT6620 transceiver chip (e.g., providing 802.11a/ac/b/g/n, Bluetooth 4.0 LE, FM, GPS; a Lapis Semiconductor® ML8511 UV sensor; a maxim integrated MAX44000 ambient light and infrared proximity sensor; a Texas Instruments® WiLink WL1283 transceiver chip (e.g., providing 802.11n, Bluetooth 3.0, FM, GPS); and/or the like. The system clock may have a crystal oscillator and generates a base signal through the computer systemization's circuit pathways. The clock may be coupled to the system bus and various clock multipliers that will increase or decrease the base operating frequency for other components interconnected in the computer systemization. The clock and various components in a computer systemization drive signals embodying information throughout the system.

The CPU is often packaged in a number of formats varying from large supercomputer(s) and mainframe(s) computers, down to mini computers, servers, desktop computers, laptops, thin clients (e.g., Chromebooks®), netbooks, tablets (e.g., Android®, iPads®, and Windows® tablets, etc.), mobile smartphones (e.g., Android®, iPhones®, Nokia®, Palm® and Windows® phones, etc.), wearable device(s) (e.g., watches, glasses, goggles (e.g., Google Glass), etc.), and/or the like. Often, the processors themselves will incorporate various specialized processing units, such as, but not limited to: integrated system (bus) controllers, memory management control units, floating point units, and even specialized processing sub-units like graphics processing units, digital signal processing units, and/or the like. Additionally, processors may include internal fast access addressable memory, and be capable of mapping and addressing memory 9929 beyond the processor itself; internal memory may include, but is not limited to: fast registers, various levels of cache memory (e.g., level 1, 2, 3, etc.), RAM, etc. The processor may access this memory through the use of a memory address space that is accessible via instruction address, which the processor can construct and decode allowing it to access a circuit path to a specific memory address space having a memory state. The CPU may be a microprocessor such as: AMD's Athlon®, Duron® and/or Opteron®; Apple's® A series of processors (e.g., A5, A6, A7, A8, etc.); ARM's® application, embedded and secure processors; IBM® and/or Motorola's DragonBall® and PowerPC®; IBM's® and Sony's® Cell processor; Intel's® 80X86 series (e.g., 80386, 80486), Pentium®, Celeron®, Core (2) Duo®, i series (e.g., i3, i5, i7, etc.), Itanium®, Xeon®, and/or XScale®; Motorola's® 680X0 series (e.g., 68020, 68030, 68040, etc.); and/or the like processor(s). The CPU interacts with memory through instruction passing through conductive and/or transportive conduits (e.g., (printed) electronic and/or optic circuits) to execute stored instructions (i.e., program code) according to various data processing techniques. Such instruction passing facilitates communication within the MLPO controller and beyond through various interfaces. Should processing requirements dictate a greater amount speed and/or capacity, distributed processors (e.g., see Distributed MLPO below), mainframe, multi-core, parallel, and/or super-computer architectures may similarly be employed. Alternatively, should deployment requirements dictate greater portability, smaller mobile devices (e.g., Personal Digital Assistants (PDAs)) may be employed.

Depending on the particular implementation, features of the MLPO may be achieved by implementing a microcontroller such as CAST's® R8051XC2 microcontroller; Intel's® MCS 51 (i.e., 8051 microcontroller); and/or the like. Also, to implement certain features of the MLPO, some feature implementations may rely on embedded components, such as: Application-Specific Integrated Circuit (“ASIC”), Digital Signal Processing (“DSP”), Field Programmable Gate Array (“FPGA”), and/or the like embedded technology. For example, any of the MLPO component collection (distributed or otherwise) and/or features may be implemented via the microprocessor and/or via embedded components; e.g., via ASIC, coprocessor, DSP, FPGA, and/or the like. Alternately, some implementations of the MLPO may be implemented with embedded components that are configured and used to achieve a variety of features or signal processing.

Depending on the particular implementation, the embedded components may include software solutions, hardware solutions, and/or some combination of both hardware/software solutions. For example, MLPO features discussed herein may be achieved through implementing FPGAs, which are a semiconductor devices containing programmable logic components called “logic blocks”, and programmable interconnects, such as the high performance FPGA Virtex® series and/or the low cost Spartan® series manufactured by Xilinx®. Logic blocks and interconnects can be programmed by the customer or designer, after the FPGA is manufactured, to implement any of the MLPO features. A hierarchy of programmable interconnects allow logic blocks to be interconnected as needed by the MLPO system designer/administrator, somewhat like a one-chip programmable breadboard. An FPGA's logic blocks can be programmed to perform the operation of basic logic gates such as AND, and XOR, or more complex combinational operators such as decoders or mathematical operations. In most FPGAs, the logic blocks also include memory elements, which may be circuit flip-flops or more complete blocks of memory. In some circumstances, the MLPO may be developed on FPGAs and then migrated into a fixed version that more resembles ASIC implementations. Alternate or coordinating implementations may migrate MLPO controller features to a final ASIC instead of or in addition to FPGAs. Depending on the implementation all of the aforementioned embedded components and microprocessors may be considered the “CPU” and/or “processor” for the MLPO.

A network interface may be regarded as a specialized form of an input output interface. Further, multiple network interfaces 9910 may be used to engage with various communications network types 9913. For example, multiple network interfaces may be employed to allow for the communication over broadcast, multicast, and/or unicast networks.

Input Output interfaces (I/O) 9908 may accept, communicate, and/or connect to user, peripheral devices 9912 (e.g., input devices 9911), cryptographic processor devices 9928, and/or the like.

The video interface composites information generated by a computer systemization and generates video signals based on the composited information in a video memory frame. Another output device is a television set, which accepts signals from a video interface. The video interface provides the composited video information through a video connection interface that accepts a video display interface (e.g., an RCA composite video connector accepting an RCA composite video cable; a DVI connector accepting a DVI display cable, etc.).

Memory

Generally, any mechanization and/or embodiment allowing a processor to affect the storage and/or retrieval of information is regarded as memory 9929. However, memory is a fungible technology and resource, thus, any number of memory embodiments may be employed in lieu of or in concert with one another. It is to be understood that the MLPO controller and/or a computer systemization may employ various forms of memory 9929. For example, a computer systemization may be configured wherein the operation of on-chip CPU memory (e.g., registers), RAM, ROM, and any other storage devices are provided by a paper punch tape or paper punch card mechanism; however, such an embodiment would result in an extremely slow rate of operation. In one configuration, memory 9929 will include ROM 9906, RAM 9905, and a storage device 9914. A storage device 9914 may be any various computer system storage. Storage devices may include: an array of devices (e.g., Redundant Array of Independent Disks (RAID)); a drum; a (fixed and/or removable) magnetic disk drive; a magneto-optical drive; an optical drive (i.e., Blueray, CD ROM/RAM/Recordable (R)/ReWritable (RW), DVD R/RW, HD DVD R/RW etc.); RAM drives; solid state memory devices (USB memory, solid state drives (SSD), etc.); other processor-readable storage mediums; and/or other devices of the like. Thus, a computer systemization generally requires and makes use of memory.

These components may be stored and accessed from the storage devices and/or from storage devices accessible through an interface bus. Although unconventional program components such as those in the component collection may be stored in a local storage device 9914, they may also be loaded and/or stored in memory such as: peripheral devices, RAM, remote storage facilities through a communications network, ROM, various forms of memory, and/or the like.

Operating System

The operating system component 9915 is an executable program component facilitating the operation of the MLPO controller. The operating system may facilitate access of I/O, network interfaces, peripheral devices, storage devices, and/or the like. The operating system may be a highly fault tolerant, scalable, and secure system such as: Apple's Macintosh OS X (Server) and macOS®; AT&T Plan 9®; Be OS®; Blackberry's QNX®; Google's Chrome®; Microsoft's Windows® 7/8/10; Unix and Unix-like system distributions (such as AT&T's UNIX®; Berkley Software Distribution (BSD)® variations such as FreeBSD®, NetBSD, OpenBSD, and/or the like; Linux distributions such as Red Hat, Ubuntu, and/or the like); and/or the like operating systems. However, more limited and/or less secure operating systems also may be employed such as Apple Macintosh OS® (i.e., versions 1-9), IBM OS/2®, Microsoft DOS®, Microsoft Windows 2000/2003/3.1/95/98/CE/Millennium/Mobile/NT/Vista/XP (Server)®, Palm OS®, and/or the like. Additionally, for robust mobile deployment applications, mobile operating systems may be used, such as: Apple's iOS®; China Operating System COS®; Google's Android®; Microsoft Windows RT/Phone®; Palm's WebOS®; Samsung/Intel's Tizen®; and/or the like. An operating system may communicate to and/or with other components in a component collection, including itself, and/or the like. Most frequently, the operating system communicates with other program components, user interfaces, and/or the like. For example, the operating system may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses. The operating system, once executed by the CPU, may enable the interaction with communications networks, data, I/O, peripheral devices, program components, memory, user input devices, and/or the like. The operating system may provide communications protocols that allow the MLPO controller to communicate with other entities through a communications network 9913. Various communication protocols may be used by the MLPO controller as a subcarrier transport mechanism for interaction, such as, but not limited to: multicast, TCP/IP, UDP, unicast, and/or the like.

Information Server

An information server component 9916 is a stored program component that is executed by a CPU. The information server may be an Internet information server such as, but not limited to Apache Software Foundation's Apache, Microsoft's Internet Information Server, and/or the like. The information server may allow for the execution of program components through facilities such as Active Server Page (ASP), ActiveX, (ANSI) (Objective-) C (++), C# and/or .NET, Common Gateway Interface (CGI) scripts, dynamic (D) hypertext markup language (HTML), FLASH, Java, JavaScript, Practical Extraction Report Language (PER_L), Hypertext Pre-Processor (PHP), pipes, Python, wireless application protocol (WAP), WebObjects®, and/or the like. The information server may support secure communications protocols such as, but not limited to, File Transfer Protocol (FTP); HyperText Transfer Protocol (HTTP); Secure Hypertext Transfer Protocol (HTTPS), Secure Socket Layer (SSL), messaging protocols (e.g., America Online (AOL) Instant Messenger (AIM)®, Application Exchange (APEX), ICQ, Internet Relay Chat (IRC), Microsoft Network (MSN) Messenger® Service, Presence and Instant Messaging Protocol (PRIM), Internet Engineering Task Force's® (IETF's) Session Initiation Protocol (SIP), SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE), open XML-based Extensible Messaging and Presence Protocol (XMPP) (i.e., Jabber® or Open Mobile Alliance's (OMA's) Instant Messaging and Presence Service (IMPS)), Yahoo! Instant Messenger® Service, and/or the like. The information server provides results in the form of Web pages to Web browsers, and allows for the manipulated generation of the Web pages through interaction with other program components. After a Domain Name System (DNS) resolution portion of an HTTP request is resolved to a particular information server, the information server resolves requests for information at specified locations on the MLPO controller based on the remainder of the HTTP request. For example, a request such as http://123.124.125.126/myInformation.html might have the IP portion of the request “123.124.125.126” resolved by a DNS server to an information server at that IP address; that information server might in turn further parse the http request for the “/myInformation.html” portion of the request and resolve it to a location in memory containing the information “myInformation.html.” Additionally, other information serving protocols may be employed across various ports, e.g., FTP communications across port 21, and/or the like. An information server may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the information server communicates with the MLPO database 9919, operating systems, other program components, user interfaces, Web browsers, and/or the like.

Access to the MLPO database may be achieved through a number of database bridge mechanisms such as through scripting languages as enumerated below (e.g., CGI) and through inter-application communication channels as enumerated below (e.g., CORBA, WebObjects, etc.). Any data requests through a Web browser are parsed through the bridge mechanism into appropriate grammars as required by the MLPO. In one embodiment, the information server would provide a Web form accessible by a Web browser. Entries made into supplied fields in the Web form are tagged as having been entered into the particular fields, and parsed as such. The entered terms are then passed along with the field tags, which act to instruct the parser to generate queries directed to appropriate tables and/or fields. In one embodiment, the parser may generate queries in SQL by instantiating a search string with the proper join/select commands based on the tagged text entries, wherein the resulting command is provided over the bridge mechanism to the MLPO as a query. Upon generating query results from the query, the results are passed over the bridge mechanism, and may be parsed for formatting and generation of a new results Web page by the bridge mechanism. Such a new results Web page is then provided to the information server, which may supply it to the requesting Web browser.

Also, an information server may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses.

User Interface

Computer interfaces in some respects are similar to automobile operation interfaces. Automobile operation interface elements such as steering wheels, gearshifts, and speedometers facilitate the access, operation, and display of automobile resources, and status. Computer interaction interface elements such as buttons, check boxes, cursors, menus, scrollers, and windows (collectively referred to as widgets) similarly facilitate the access, capabilities, operation, and display of data and computer hardware and operating system resources, and status. Operation interfaces are called user interfaces. Graphical user interfaces (GUIs) such as the Apple's iOS®, Macintosh Operating System's Aqua®; IBM's OS/2®; Google's Chrome® (e.g., and other webbrowser/cloud based client OSs); Microsoft's Windows® varied UIs 2000/2003/3.1/95/98/CE/Millenium/Mobile/NT/Vista/XP (Server) (i.e., Aero, Surface, etc.); Unix's X-Windows (e.g., which may include additional Unix graphic interface libraries and layers such as K Desktop Environment (KDE), mythTV and GNU Network Object Model Environment (GNOME)), web interface libraries (e.g., ActiveX, AJAX, (D)HTML, FLASH, Java, JavaScript, etc. interface libraries such as, but not limited to, Dojo, jQuery(UI), MooTools, Prototype, script.aculo.us, SWFObject, Yahoo! User Interface®, any of which may be used and) provide a baseline and means of accessing and displaying information graphically to users.

Also, in place of a Web browser and information server, a combined application may be developed to perform similar operations of both. The combined application would similarly affect the obtaining and the provision of information to users, user agents, and/or the like from the MLPO enabled nodes. The combined application may be nugatory on systems employing Web browsers.

Mail Server

A mail server component 9921 is a stored program component that is executed by a CPU 9903. The mail server may be an Internet mail server such as, but not limited to: dovecot, Courier IMAP, Cyrus IMAP, Maildir, Microsoft Exchange, sendmail, and/or the like.

Generally, the mail client provides a facility to compose and transmit electronic mail messages.

Cryptographic Server

A cryptographic server component 9920 is a stored program component that is executed by a CPU 9903, cryptographic processor 9926, cryptographic processor interface 9927, cryptographic processor device 9928, and/or the like. Cryptographic processor interfaces will allow for expedition of encryption and/or decryption requests by the cryptographic component; however, the cryptographic component, alternatively, may run on a CPU. The cryptographic component allows for the encryption and/or decryption of provided data. The cryptographic component allows for both symmetric and asymmetric (e.g., Pretty Good Protection (PGP)) encryption and/or decryption. The cryptographic component may employ cryptographic techniques such as, but not limited to: digital certificates (e.g., X.509 authentication framework), digital signatures, dual signatures, enveloping, password access protection, public key management, and/or the like. The cryptographic component will facilitate numerous (encryption and/or decryption) security protocols such as, but not limited to: checksum, Data Encryption Standard (DES), Elliptical Curve Encryption (ECC), International Data Encryption Algorithm (IDEA), Message Digest 5 (MDS, which is a one way hash operation), passwords, Rivest Cipher (RC5), Rijndael, RSA (which is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman), Secure Hash Algorithm (SHA), Secure Socket Layer (SSL), Secure Hypertext Transfer Protocol (HTTPS), Transport Layer Security (TLS), and/or the like. Employing such encryption security protocols, the MLPO may encrypt all incoming and/or outgoing communications and may serve as node within a virtual private network (VPN) with a wider communications network. The cryptographic component facilitates the process of “security authorization” whereby access to a resource is inhibited by a security protocol wherein the cryptographic component effects authorized access to the secured resource. In addition, the cryptographic component may provide unique identifiers of content, e.g., employing and ATD5 hash to obtain a unique signature for a digital audio file. A cryptographic component may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. The cryptographic component supports encryption schemes allowing for the secure transmission of information across a communications network to allow the MLPO component to engage in secure transactions if so desired. The cryptographic component facilitates the secure accessing of resources on the MLPO and facilitates the access of secured resources on remote systems; i.e., it may act as a client and/or server of secured resources. Most frequently, the cryptographic component communicates with information servers, operating systems, other program components, and/or the like. The cryptographic component may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses.

The MLPO Database

The MLPO database component 9919 may be embodied in a database and its stored data. The database is a stored program component, which is executed by the CPU; the stored program component portion configuring the CPU to process the stored data. The database may be a fault tolerant, relational, scalable, secure database such as MySQL®, Oracle®, Sybase®, etc. may be used. Additionally, optimized fast memory and distributed databases such as IBM's Netezza®, MongoDB's MongoDB®, opensource Hadoop®, opensource VoltDB, SAP's Hana®, etc. Relational databases are an extension of a flat file. Relational databases consist of a series of related tables. The tables are interconnected via a key field. Use of the key field allows the combination of the tables by indexing against the key field; i.e., the key fields act as dimensional pivot points for combining information from various tables. Relationships generally identify links maintained between tables by matching primary keys. Primary keys represent fields that uniquely identify the rows of a table in a relational database. Alternative key fields may be used from any of the fields having unique value sets, and in some alternatives, even non-unique values in combinations with other fields. More precisely, they uniquely identify rows of a table on the “one” side of a one-to-many relationship.

Alternatively, the MLPO database may be implemented using various other data-structures, such as an array, hash, (linked) list, struct, structured text file (e.g., XML), table, and/or the like. Such data-structures may be stored in memory and/or in (structured) files. In another alternative, an object-oriented database may be used, such as Frontier™, ObjectStore, Poet, Zope, and/or the like. Object databases can include a number of object collections that are grouped and/or linked together by common attributes; they may be related to other object collections by some common attributes. Object-oriented databases perform similarly to relational databases with the exception that objects are not just pieces of data but may have other types of capabilities encapsulated within a given object. If the MLPO database is implemented as a data-structure, the use of the MLPO database 9919 may be integrated into another component such as the MLPO component 9935. Also, the database may be implemented as a mix of data structures, objects, and relational structures. Databases may be consolidated and/or distributed in countless variations (e.g., see Distributed MLPO below). Portions of databases, e.g., tables, may be exported and/or imported and thus decentralized and/or integrated.

In one embodiment, the MLPO database may interact with other database systems. For example, employing a distributed database system, queries and data access by search MLPO component may treat the combination of the MLPO database, an integrated data security layer database as a single database entity (e.g., see Distributed MLPO below).

In one embodiment, user programs may contain various user interface primitives, which may serve to update the MLPO. Also, various accounts may require custom database tables depending upon the environments and the types of clients the MLPO may need to serve. It should be noted that any unique fields may be designated as a key field throughout. In an alternative embodiment, these tables have been decentralized into their own databases and their respective database controllers (i.e., individual database controllers for each of the above tables). Employing various data processing techniques, one may further distribute the databases over several computer systemizations and/or storage devices. Similarly, configurations of the decentralized database controllers may be varied by consolidating and/or distributing the various database components 9919 a-z. The MLPO may be configured to keep track of various settings, inputs, and parameters via database controllers.

The MLPO database may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the MLPO database communicates with the MLPO component, other program components, and/or the like. The database may contain, retain, and provide information regarding other nodes and data.

The MLPOs

The MLPO component 9935 is a stored program component that is executed by a CPU. In one embodiment, the MLPO component incorporates any and/or all combinations of the aspects of the MLPO that was discussed in the previous figures. As such, the MLPO affects accessing, obtaining and the provision of information, services, transactions, and/or the like across various communications networks. The features and embodiments of the MLPO discussed herein increase network efficiency by reducing data transfer requirements the use of more efficient data structures and mechanisms for their transfer and storage. As a consequence, more data may be transferred in less time, and latencies with regard to transactions, are also reduced. In many cases, such reduction in storage, transfer time, bandwidth requirements, latencies, etc., will reduce the capacity and structural infrastructure requirements to support the MLPO's features and facilities, and in many cases reduce the costs, energy consumption/requirements, and extend the life of MLPO's underlying infrastructure; this has the added benefit of making the MLPO more reliable. Similarly, many of the features and mechanisms are designed to be easier for users to use and access, thereby broadening the audience that may enjoy/employ and exploit the feature sets of the MLPO; such ease of use also helps to increase the reliability of the MLPO. In addition, the feature sets include heightened security as noted via the Cryptographic components 9920, 9926, 9928 and throughout, making access to the features and data more reliable and secure

The MLPO transforms machine learning simulation request, decision tree ensembles training request, expected returns calculation request, portfolio construction request, predefined scenario construction request, portfolio returns visualization request inputs, via MLPO components (e.g., MLSSP, DTET, ERC, PC, PSC, SPRV, BPRV, PRV, ARMC), into machine learning simulation response, decision tree ensembles training response, expected returns calculation response, portfolio construction response, predefined scenario construction response, portfolio returns visualization response outputs.

The MLPO component enabling access of information between nodes may be developed by employing various development tools and languages such as, but not limited to: Apache® components, Assembly, ActiveX, binary executables, (ANSI) (Objective-) C (++), C# and/or .NET, database adapters, CGI scripts, Java, JavaScript, mapping tools, procedural and object oriented development tools, PERL, PHP, Python, shell scripts, SQL commands, web application server extensions, web development environments and libraries (e.g., Microsoft's® ActiveX; Adobe® AIR, FLEX & FLASH; AJAX; (D)HTML; Dojo, Java; JavaScript; jQuery(UI); MooTools; Prototype; script.aculo.us; Simple Object Access Protocol (SOAP); SWFObject; Yahoo!® User Interface; and/or the like), WebObjects®, and/or the like. In one embodiment, the MLPO server employs a cryptographic server to encrypt and decrypt communications. The MLPO component may communicate to and/or with other components in a component collection, including itself, and/or facilities of the like. Most frequently, the MLPO component communicates with the MLPO database, operating systems, other program components, and/or the like. The MLPO may contain, communicate, generate, obtain, and/or provide program component, system, user, and/or data communications, requests, and/or responses.

Distributed MLPOs

The structure and/or operation of any of the MLPO node controller components may be combined, consolidated, and/or distributed in any number of ways to facilitate development and/or deployment. Similarly, the component collection may be combined in any number of ways to facilitate deployment and/or development. To accomplish this, one may integrate the components into a common code base or in a facility that can dynamically load the components on demand in an integrated fashion. As such a combination of hardware may be distributed within a location, within a region and/or globally where logical access to a controller may be abstracted as a singular node, yet where a multitude of private, semiprivate and publicly accessible node controllers (e.g., via dispersed data centers) are coordinated to serve requests (e.g., providing private cloud, semi-private cloud, and public cloud computing resources) and allowing for the serving of such requests in discrete regions (e.g., isolated, local, regional, national, global cloud access).

The component collection may be consolidated and/or distributed in countless variations through various data processing and/or development techniques. Multiple instances of any one of the program components in the program component collection may be instantiated on a single node, and/or across numerous nodes to improve performance through load-balancing and/or data-processing techniques. Furthermore, single instances may also be distributed across multiple controllers and/or storage devices; e.g., databases. All program component instances and controllers working in concert may do so through various data processing communication techniques.

The configuration of the MLPO controller will depend on the context of system deployment. Factors such as, but not limited to, the budget, capacity, location, and/or use of the underlying hardware resources may affect deployment requirements and configuration. Regardless of if the configuration results in more consolidated and/or integrated program components, results in a more distributed series of program components, and/or results in some combination between a consolidated and distributed configuration, data may be communicated, obtained, and/or provided. Instances of components consolidated into a common code base from the program component collection may communicate, obtain, and/or provide data. This may be accomplished through intra-application data processing communication techniques such as, but not limited to: data referencing (e.g., pointers), internal messaging, object instance variable communication, shared memory space, variable passing, and/or the like. For example, cloud services such as Amazon Data Services®, Microsoft Azure®, Hewlett Packard Helion®, IBM® Cloud services allow for MLPO controller and/or MLPO component collections to be hosted in full or partially for varying degrees of scale.

If component collection components are discrete, separate, and/or external to one another, then communicating, obtaining, and/or providing data with and/or to other component components may be accomplished through inter-application data processing communication techniques such as, but not limited to: Application Program Interfaces (API) information passage; (distributed) Component Object Model ((D)COM), (Distributed) Object Linking and Embedding ((D)OLE), and/or the like), Common Object Request Broker Architecture (CORBA), Jini local and remote application program interfaces, JavaScript Object Notation (JSON), Remote Method Invocation (RAE), SOAP, process pipes, shared files, and/or the like. Messages sent between discrete component components for inter-application communication or within memory spaces of a singular component for intra-application communication may be facilitated through the creation and parsing of a grammar A grammar may be developed by using development tools such as lex, yacc, XML, and/or the like, which allow for grammar generation and parsing capabilities, which in turn may form the basis of communication messages within and between components.

For example, a grammar may be arranged to recognize the tokens of an HTTP post command, e.g.:

-   -   w3c -post http:// . . . Value1

where Value1 is discerned as being a parameter because “http://” is part of the grammar syntax, and what follows is considered part of the post value. Similarly, with such a grammar, a variable “Value1” may be inserted into an “http://” post command and then sent. The grammar syntax itself may be presented as structured data that is interpreted and/or otherwise used to generate the parsing mechanism (e.g., a syntax description text file as processed by lex, yacc, etc.). Also, once the parsing mechanism is generated and/or instantiated, it itself may process and/or parse structured data such as, but not limited to: character (e.g., tab) delineated text, HTML, structured text streams, XML, and/or the like structured data. In another embodiment, inter-application data processing protocols themselves may have integrated parsers (e.g., JSON, SOAP, and/or like parsers) that may be employed to parse (e.g., communications) data. Further, the parsing grammar may be used beyond message parsing, but may also be used to parse: databases, data collections, data stores, structured data, and/or the like. Again, the desired configuration will depend upon the context, environment, and requirements of system deployment.

For example, in some implementations, the MLPO controller may be executing a PHP script implementing a Secure Sockets Layer (“SSL”) socket server via the information server, which listens to incoming communications on a server port to which a client may send data, e.g., data encoded in JSON format. Upon identifying an incoming communication, the PHP script may read the incoming message from the client device, parse the received JSON-encoded text data to extract information from the JSON-encoded text data into PHP script variables, and store the data (e.g., client identifying information, etc.) and/or extracted information in a relational database accessible using the Structured Query Language (“SQL”). An exemplary listing, written substantially in the form of PHP/SQL commands, to accept JSON-encoded input data from a client device via an SSL connection, parse the data to extract variables, and store the data to a database, is provided below:

<?PHP header(′Content-Type: text/plain′); // set ip address and port to listen to for incoming data $address = ‘192.168.0.100’; $port = 255; // create a server-side SSL socket, listen for/accept incoming communication $sock = socket_create(AF_INET, SOCK_STREAM, 0); socket_bind($sock, $address, $port) or die(‘Could not bind to address'); socket_listen($sock); $client = socket_accept($sock); // read input data from client device in 1024 byte blocks until end of message do { $input = “”; $input = socket_read($client, 1024); $data .= $input; } while($input != “”); // parse data to extract variables $obj = json_decode($data, true); // store input data in a database mysql_connect(″201.408.185.132″,$DBserver,$password); // access database server mysql_select(″CLIENT_DB.SQL″); // select database to append mysql_query(“INSERT INTO UserTable (transmission) VALUES ($data)”); // add data to UserTable table in a CLIENT database mysql_close(″CLIENT_DB.SQL″); // close connection to database ?>
